My above test was with the sstfb driver built-in into the kernel and with all
other graphics drivers (incl. stifb and STI text console) disabled.

FYI, this is what my graphics-relevant part of .config looked like:
#
# Graphics support
#
CONFIG_FB=y
# CONFIG_FB_CIRRUS is not set
# CONFIG_FB_PM2 is not set
# CONFIG_FB_CYBER2000 is not set
# CONFIG_FB_IMSTT is not set

Then, in a second test I enabled STIFB, and choosed SSTFB as module.
Booting up worked:

.... (the second card 'A1262A' is a Visualize FX4 - it doesn't work!)

c3000:~# modprobe sstfb
sstfb: Voodoo2 (revision 2) with ICS ICS5342 dac
sstfb: framebuffer at 0xfb400000, mapped to 0xfb400000, size 2MB

c3000:~# cat /proc/fb 
0 stifb
1 Voodoo2

Works too...
