Following up to my own note:  With no visible change to dmesg, the audio 
now appears to work at least pretty well, maybe a little chop but acceptable 
with no changes to pci.c; maybe some acpi change fixed it?  Music plays at 
least fairly well now, but the X-windows beep function (using kde + artsd) 
still seems rather delayed but now completely non-choppy.

However, the firewire and memory-stick are still listed as missing in
action...  I can't burn a cd using my usb drive since this laptop doesn't
support ehci (can send the files to another computer with an internal
drive).

I will check this again, but I am pretty sure that I have plug-and-play OS 
turned ON in my bios since last summer when the acpi started working fairly 
well.  How is this supposed to be set now on non-acpi motherboards (I have
several such that run current; one Aladdin-5 K6-2 (ASUS has acpi, but at
least one of my "cheap" ones doesn't), and an embedded-controller (Cyrix GX) 
mini-system)?
