Hi.

I have tried to make a hack to remove support USER_MODE.
Result: +10% speed up.
 From "checkit" test (REMOVED_USER_MODE/Original Qemu)
CPU:        1000825/98222
FPU:        46374.5/43146.3
VGA BIOS:     25273/24590
VGA direct:  922850/901061
HD direct:  89902.8/68978.7

The method is: removed all "env" usage.
ftp://ftp.simtreas.ru/pub/my/qemu/
have nouserhack.sh for demonstrate changes
to I386-I386-softmmu qemu.

Also. I have placed "checkit" to ftp.
Its a check program show problem with test cirrus-VGA for
some old modes, original VGA emulator give more true.

(Warning, AIO_patch from this URL very outdate. Don`t use,
for demo only!)
