i have had trouble with vesa cursor in 1600x1200. generally when
i have trouble, the cursor won't move at all. one problem i
did not finish looking at were the spill-over bits in vga register 13.
nvidia is slow, but have you tried with the newly-integrated mtrr or
the pat stuff? my pentium iv terminal is pretty snappy in 1600x1200x32 + pat
my amd terminal with a pcie card + pat is even snapper, until the screen is read.
one of these days i'll figure out why the radeon driver is broken for me and/or
integrate aki's double buffer. even with WT memory, that only speeds the
write path.
