I do not think that it matters. ide0 sees its disks just
fine. ide1 had no problems in the past. It is only when the
adaptor is plugged in that this problem is seen. Nevertheless,
this is an ICH5:

0000:00:1f.1 IDE interface: Intel Corp. 82801EB/ER (ICH5/ICH5R) Ultra ATA 100 Storage Controller (rev 02)

I added 'ide1=ata66' and it did not help. I also got the messages:

Kernel command line: BOOT_IMAGE=2.6.14.3 ro root=306 console=ttyS0,38400 console=tty0 irqpoll ide1=ata66 single
ide_setup: ide1=ata66 -- OBSOLETE OPTION, WILL BE REMOVED SOON!
