I don't have either APM or PCMCIA installed though.

Nov 21 22:12:53 acidlake kernel: UM8886BF: IDE controller on PCI bus 00 dev 91
Nov 21 22:12:53 acidlake kernel: UM8886BF: not 100% native mode: will probe irqs later
Nov 21 22:12:53 acidlake kernel: hda: SAMSUNG SHD-3122A (APOLLO), ATA DISK drive
Nov 21 22:12:53 acidlake kernel: ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
Nov 21 22:12:53 acidlake kernel: hda: SAMSUNG SHD-3122A (APOLLO), 240MB w/64kB Cache, CHS=937/15/35
