That change in itself should do nothing, it only sets an upper limit
on the clock you are allowed to use in a monitor entry; if the monitor
entry says 'clock=135' it shouldn't make any difference.

The ways in which the S3 968 and TVP3026 can be configured together
vary between boards and there are some tweaks available if you look in
/sys/src/cmd/aux/vga/vision968.c ('disa1sc=1' is one of the tweaks).
If the cursor hangs reliably with the new database entry even after
a clean reboot, I'd just go back to the one that works.
