Hi everybody i try to use Windows NT 4.0
with qemu.

I tested with qemu 0.10.6 and vm crash on screen resolution resize
(switch from 640x480 16bits to 1280x1024 65536).

I made the same test with qemu 0.9.1 and it works well.
find attached gdb qemu 0.10.6 trace about cirrus crash.

please can you fix it ?
