Mmm... actually, the "-dsat" flag seems to make smartctl mostly work with and without the patch. This is on 2.6.25.6 on my notebook here. Some month I'll update the kernel and fix VMware and wireless again for a newer kernel, but for now that's what it runs.
Here's hdparm --verbose, sans patch:
hdparm --verbose -I /dev/sdb
/dev/sdb: outgoing cdb: 85 08 2e 00 00 00 00 00 00 00 00 00 00 40 ec 00 SG_IO: ATA_16 status=0x2, host_status=0x0, driver_status=0x8 SG_IO: sb[] = {72 00 00 00 00 00 00 0e} SG_IO: desc[] = {09 0c .. } ATA_16 tf->status=0x00 tf->error=0x00
ATA device, with non-removable media Model Number: Hitachi HTS541612J9SA00 Serial Number: SB2D11E4GESWAB Firmware Revision: SBDOC74P ...
And here is smartctl -a -dsat, without the -T permissive flag:
