Should not be required.

I think you would be better off simply adding the acpi hint rather than
modifying the APM entry, but this is cosmetic. I changed the apm line to
hint.apm.0.disabled="0"

On my T30 I have:
hw.ata/atapi_dma="1"
hw.cbb.start_memory="0x20000000"
I tried hw.pci.allow_unsupported_io_range="1", but it did not seem to
help. The sound on the T30 is an ICH3. To get it to work I added smbus
support to the kernel.
device	smbus
device	ichsmb
device	smb
device	pcm

See my response to Robert Watson's post for a work-around.

Try turning on the SMBus as above.

Works fine for me. Is the kernel built with the wi driver? I normally
load the driver (if_wi) at boot time.

Does the card probe? If so, what is reported? Do you get a printout
of the firmware level?

This is disturbing as I have been seeing similar problems on my T30 for
a week. Attempting to buildworld bombs after 3 or 4 minutes in various
places. memtest86 found no memory problems. I have not run any CPU
diagnostics, but was assuming a hardware problem. (I still am).

Unlike my previous experience with this sort of thing, it seems to
happen about the same whether the system is hot or cold.

Has any A or T series ThinkPad owner built a new CURRENT system over the
past week?
