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

local buffer
*/
 
                *FADT2 = *((fadt_descriptor_rev2*) acpi_gbl_FADT);

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