'+cur' means this driver includes a hardware cursor section;
'=cur' means this driver is only for a hardware cursor.
You may also want to make the following changes to vganvidia.c to make
the cursor behave 'properly' at the screen edges.

The only other problem I see is that when you move the cursor around
continuously there's sometimes a flash of an uninitialised (mostly white)
cursor. Maybe it's just my card:

All in all, a nice contribution, thank you.
