Could it be I'm just having problems using Linuxbios & Filo under Qemu emulation instead of actually booting from a flash device?
Anyways, here's my debug info:
I'm successfully using Qemu to load Linuxbios with a filo payload specifying "hdc1" as my CD-ROM device within the Filo Config file.
/dev/hdc = DVD-ROM with DVD+R LiveCD /dev/hdd = CD-ROM with CD-R LiveCD
Using an actual CD-ROM (DVD-ROM) device with the Qemu "-cdrom /dev/hdc" option :
$ /home/roger/tmp/qemu/bin/qemu -L ~ -nographic -cdrom /dev/hdc -boot d
