I tried to test 4/300 card, but the power supply has failed in my 4/330.
I'm still puzzled as to exactly what causes the size error for the P4 bus
write.  Like last time, we could try by trial and error, but it might be
an extended process.

David's suggestion is good though - if you can check that it boots with an
earlier kernel, then we could look at the differences in the P4 bus setup,
which would give us a good starting point.

Regards,

Julian

PS.  I'll look for somewhere to get my PSU repaired, but that might not be
soon.  I also only have monochrome P4 framebuffers (CG2, MG3, MG4) as my
CG4 failed a long time ago.
