XFree86 hangs machine on exit

I just had a look at the source and commented out the line

        memset(pSmi->FBBase, 0, 256 * 1024);    /* #689 */

in SMI_LeaveVT() in file
This solves the problem for me. No more hangs -- until now...
I have no idea though, what the memset() was good for in the first place,
and why it seems to cause trouble on BSD but not on Linux.


PS: I also had strange colors on my screen, when the machine locked up. No
motion though. It just locks.
