Yup, got that.

I'll try. The next device that shows up with INSTALL_ACPI is fdc0. The ... 
confusing thing is that INSTALL_ACPI works so well.

I spent some time with the ULTRA40 config that Kurt Schreiner posted (over in 
the "opteron 246 system" thread that I started). Here's my H8DCE config. I note 
that GENERIC_ACPI doesn't turn off MPBIOS and doesn't turn on ACPI_SCANPCI or 
PCI_INTR_FIXUP - that doesn't seem right...

Of course, this doesn't boot properly, either, but it crashes in a different 
place. dmesg follows.

I turned on a number of acpi devices; that might be a mistake - especially since 
past kernels have found attimer (the likely next device) at isa. I'll undo that.

Karl points out that I've lost about 1G of memory, and thinks that has to do 
with the "pci mem hole". This is voodoo for me - suggestions welcome. But I'd 
really love to get the machine running, first!
