>From the other docs it appears 0x122E is the ISA bridge and this laptop
has 0x122E (PIIX bridge) and an 82437MX system controller, but no PIIX
IDE. That actually suggests its more like the "MPIIX" which has a PIO
only IDE controller existing (logically anyway) on the ISA side of the
system.
That would explain the observed behaviour and fit with the pattern of
PCI identifiers. Now to hunt 82437 docs.
(In the mean time try adding the 0x1235 id to the 2.6.17-mm kernel in
drivers/scsi/pata_mpiix and see if that works with the new libata layer
not drivers/ide).
