Sweet smell of success: 

Jan  6 22:09:20 sodium kernel: fb1: S3 Virge/GX on 0000:00:03.0, 6 MB
RAM, 14 MHz MCLK

s3fb now loads OK and correctly identifies the graphic adapter, now that
I fixed s3_identification and others. 

It now crashes elsewhere when the framebuffer device is opened, the logs
shows that:

Looks like there's a bug in save_vga which is in
drivers/video/vgastate.c. I'll be sprinkling printk()s through
save_vga() to find the offending line of code.

Still, I'm pleased the module loads.
