I had the problem and just solved it, thanks to a user on
comp.os.linux.portable.
It turns out that this is an ACPI problem--all that's needed is a quick
patch to the kernel source:
You'll need to modify drivers/acpi/tables/tbconvrt.c in your kernel
source tree. Here's my diff:
--- tbconvrt.c.ori Sun Feb 10 17:50:23 2002

This was sufficient to get basic
sound working correctly--even with a
framebuffer console (although I
haven't tried framebuffer X recently).
