A newer version than the one I have. Looks like there's at least one newer chip revision than the 0x11 that I have too.
Just need to add something like this to get it to compile.

My set up is a IT8212 PCI card running two UDMA133 discs in software RAID0. I'd like to test the smart RAID some time, but that isn't really practical at the moment.
IT8212: IDE controller at PCI slot 0000:00:0c.0 ACPI: PCI interrupt 0000:00:0c.0[A] -> GSI 17 (level, low) -> IRQ 17 IT8212: chipset revision 17 IT8212: 100% native mode on irq 17 That makes sense.
ide2: BM-DMA at 0xec00-0xec07, BIOS settings: hde:pio, hdf:pio it8212: controller in RAID mode.
That doesn't. I have no RAID sets defined in the IT8212 card BIOS. BTW, the BIOS is an old one and should be updated. However when I tried the updater claimed success, but on reboot it hadn't changed.
ide3: BM-DMA at 0xec08-0xec0f, BIOS settings: hdg:pio, hdh:pio hde: Maxtor 6Y120P0, ATA DISK drive it8212: selected 50MHz clock.
Nor does this as it really should be using the 66MHz clock setting.
ide2 at 0xb000-0xb007,0xa802 on irq 17 hde: max request size: 128KiB hde: recal_intr: status=0x51 { DriveReady SeekComplete Error } hde: recal_intr: error=0x04 { DriveStatusError } Any idea what could be causing this? My hacked driver doesn't get this in 2.6.7, but then it could be a 2.6.8 problem.
hde: 240121728 sectors (122942 MB) w/7936KiB Cache, CHS=65535/16/63, UDMA(33)
Oddly my driver reports UDMA(33) too, but that's probably bad coding as it is definitely running faster than that.
/dev/ide/host2/bus0/target0/lun0: p1 p2 hdg: Maxtor 6Y120P0, ATA DISK drive it8212: selected 50MHz clock. ide3 at 0xa400-0xa407,0xa002 on irq 17 hdg: max request size: 128KiB hdg: recal_intr: status=0x51 { DriveReady SeekComplete Error } hdg: recal_intr: error=0x04 { DriveStatusError } hdg: 240121728 sectors (122942 MB) w/7936KiB Cache, CHS=65535/16/63, UDMA(33) /dev/ide/host2/bus1/target0/lun0: p1 p2 And the same speed problems again.
Now some speed tests with hdparm
# hdparm -Tt /dev/hd[eg] /dev/md[01]
/dev/hde: Timing buffer-cache reads: 3016 MB in 2.00 seconds = 1505.97 MB/sec Timing buffered disk reads: 86 MB in 3.02 seconds = 28.49 MB/sec
/dev/hdg: Timing buffer-cache reads: 3012 MB in 2.00 seconds = 1504.72 MB/sec Timing buffered disk reads: 86 MB in 3.02 seconds = 28.46 MB/sec
/dev/md0: Timing buffer-cache reads: 2928 MB in 2.00 seconds = 1462.03 MB/sec Timing buffered disk reads: 156 MB in 3.01 seconds = 51.90 MB/sec
/dev/md1: Timing buffer-cache reads: 2996 MB in 2.00 seconds = 1495.98 MB/sec Timing buffered disk reads: 156 MB in 3.01 seconds = 51.77 MB/sec
So I guess it actually is running at 33MHz!
Current results with my hack
# hdparm -Tt /dev/hd[eg] /dev/md[01]
/dev/hde: Timing buffer-cache reads: 2980 MB in 2.00 seconds = 1488.74 MB/sec Timing buffered disk reads: 172 MB in 3.02 seconds = 57.04 MB/sec
/dev/hdg: Timing buffer-cache reads: 2988 MB in 2.00 seconds = 1493.48 MB/sec Timing buffered disk reads: 170 MB in 3.03 seconds = 56.15 MB/sec
/dev/md0: Timing buffer-cache reads: 2964 MB in 2.00 seconds = 1480.74 MB/sec Timing buffered disk reads: 286 MB in 3.00 seconds = 95.25 MB/sec
/dev/md1: Timing buffer-cache reads: 2924 MB in 2.00 seconds = 1460.03 MB/sec Timing buffered disk reads: 290 MB in 3.01 seconds = 96.33 MB/sec
