In addition to what Johannes said - it seems that the driver does work
on some notebooks. The problem you described seems to be the rage clock
detection problem. Please use the latest 1.4.3 pre-release which fixed
this problem, or use 1.4.2 and try both with and without the
ragedoubleclock option.

Again, most mach 64 cards fail completely with the vesa driver (computer
locks completely, reset necessary), while some work.
