[RFC] vm86 bugs in 2.5.30

[Kasper Dupont]

I'm trying to port the vm86 bugfixes from 2.4.19 to 2.5.30.
A premature patch is available at:
http://www.daimi.au.dk/~kasperd/linux_kernel/vm86.2.5.30.patch
The second chunk in mark_screen_rdonly had to be applied by
hand, so I'd appreachiate if whoever made that bugfix would
verify I got the patch applied correctly.

I am however currently fighting with another vm86 problem.
I get this oops on 2.5.30:

<4> invalid operand: 0000

>>EIP; 00000000 Before first symbol
Trace; c0108c87 <syscall_call+7/b>

It happens during the vm86 system call, but it is not fixed
by any of the changes in vm86.c. Who remember which patch
fixed this problem?
