I have experienced a similar problem and haven't sorted it out yet.

When I boot my custom 2.2.7 kernel it says that wdc1 is at 0x170-0x177 irq 15 on isa. However, when I boot the 3.0 generic kernel I get a message along the lines of wdc1 not found at 0x170. As far as I can tell the kernel is looking for wdc1 but can't find it. I also have an Adaptec 1542 SCSI controller installed and it is found and works. The other observation is that around the place where the PCI stuff is detected (right at the start of the boot sequence) it says something like "the second ide controller does not support direct DMA access." I was going to build a new 3.0 kernel to see if that would help, but I ran into a compilation error. I don't have the message in front of me right now, but it seemed to relate to the SCSI support and said something like "units should be in seconds, not milliseconds, change and recompile." (I might have the order reversed.) I ran out of time and didn't have a chance to check the message out further.
