you are using vesa mode because monitor=vesa.  you need to set
your monitor.  information on doing that is in vgadb(6).  once your
monitor information is set properly, the correct driver should be used.

to check for dma, "cat /dev/sdC0/ctl".  you will see dma x dmactl y.
x describes the dma capabilities of the drive, y describes which dma
capabilities are being used.  so if x is nonzero but y is zero then
"echo -n dma on > /dev/sdC0/ctl" will turn dma on.  this can be 
done automatically through plan9.ini.  "man plan9.ini" for more info.
