The patch has worked fine and here are my results before and after
installing the kernel. The machine is a PII 350MHz and a G400 DualHead MAX

Sorry but the results look similar but I could have messed something up
alone the way, so I shall rebuild and reinstall the kernel and the CVS
DirectFB from scratch. With the fusion patch and the the G400 clock patch.
Something that I didn't quite get was the addition of matrox:init to the
kernel, it changed the display size back to 80x25. Anyway the lilo config
line is:
append="hdd=ide-scsi video=matrox:init:vesa:0x11A,mtrr,ywrap"
I haven't applied the 32MB patch, well I had and then took it out because
the screen went funny after scrolling a few pages in either direction.
