Well, it works with plain 2.6.0-test6.

Unfortunately it fails with ruby. :-(

Seems an extra card is cheaper then. :-)

2.6.0-test6-ruby dies before the first printk if I do that, 
while 2.6.0-test6 works.  fbcon on matrox breaks somehow
with ruby.  I don't know what to do to debug this
further - adding printk's is probably not an option.

Thanks!  I'll do this if I ever get those
fbconsoles working.
