 While I was playing around, I compiled a version of the kernel with ACPI taken
 out completely, and the system booted happily with no intervention required on
 my part.
 
 On the Dell, I fonud a setting for "PowerNow!" in the bios.  I disabled it,
 recompiled a GENERIC kernel, and sure enough, the system booted without any
 problems.

 Did you disable ohci in the bios or in your kernel configuration somewhere?

 I grabbed the patch (ran cvs update before compiling the GENERIC kernel).  Is
 this also used on the amd64 architecture?
 
 Thanks a million for your help.
