[LinuxBIOS] FILO Enabling VIA_SOUND breaks keyboard in Linux? [VIA EPIA-M10000]

further experimenting with EPIA-M10000: I am using the default FILO 
0.4.2 "Config" for x86, except for the AUTOBOOT_FILE which I have set to:

AUTOBOOT_FILE = "hdc1:/vmlinuz-2.6.12-10-386 
initrd=hdc1:/initrd.img-2.6.12-10-386 root=/dev/hdc2 ro vga=771 
console=tty0 console=ttyS0,115200"

This time I tried enabling sound:


During booting it reported "No sound device found".*

The next problem was I had keyboard control during the FILO console, but 
no longer in Linux. When I changed back to disabling sound and 
reflashing LinuxBIOS, this problem dissappeared. I have then fully 
reproduced this whole sequence again from the start.

Can the FILO sound probe do this? I thought it is merely scanning PCI?
