Isn't always there the possibility to add a hwcursor also?. I think hw
cursors are directly supported by VESA standards, but I think one
thing is independant from another. Isn't it possible to use VESA for
mode switching or whatever and reduce the code you have to write for
the card to write the hwcursor support?.

Another question. What is the software cursor really necessary for?
(other than in vmware). Do there really exist modern cards
which don't support hardware cursor?.
