My guess is you also have an ATAPI CD-ROM as master on first channel of
wdc0, or some other (bootable) device - this combination (to a reason
unknown to me - is it MB fault or someone elses...) results in bootloader
wrongly assuming it's being booted off the wd0.

You can defeat it by specifying -a flag, and then responsing with 'da0' to
the prompt asking which device to mount on root. This is only a
workaround, not a solution - I'll have to investigate it more before
giving you any other advice...
