I believe the best solution would be to change /sys/lib/dist/pc/sub/vmware from

    #!/bin/rc

    if(aux/isvmware -s){
           echo -n off >'#P/i8253timerset'
           for(i in '#S'/sd??)
                   if(test -f $i/ctl)
                           echo dma on >$i/ctl
    }

to

    if(aux/isvmware -s){
           echo -n off >'#P/i8253timerset'
           echo hwaccel off >'#v/vgactl'
    }

That is, add the line that disables hardware acceleration, and remove the lines that set dma on (this is handled by /sys/lib/dist/pc/sub/termrc already).

I do have one question though: when setting dma on, /sys/lib/dist/pc/sub/termrc iterates over /dev/sd*/ctl, while /sys/lib/dist/pc/sub/vmware iterates over '#S'/sd??; is there a specific reason vmware needs to use '#S' rather than /dev? (Or to formulate the question a bit different: I'd expect that '#S' is bound to /dev at that point regardless of whether we're using vmware or not; is this correct?)

Greetings, Sander.
