I tested only with NeXTStep 3.3 booting from hard disk and it worked. I'll test the rest today but considering the PS/2 mouse emulation is not working (there is a bug in it that prevents NeXTStep PS/2 mouse driver and old X11 PS/2 mouse drivers working). But for now, it boots up to the GUI flawlessly.

Ok so in resume we have the following PS/2 mouse bugs: NeXTStep and OpenStep PS/2 driver receives no movement at all from the mouse (Darwin PS/2 driver seems to be made from scratch so no helpful here). MS-DOS Mouse driver hangs the whole machine. Windows Me Setup mouse driver receives no movement at all from the mouse. Old XFree86 PS/2 mouse driver receives no movement at all from standard protocols (PS/2, IMPS/2) or random movements (Microsoft). Hydrogen OS mouse driver does not work. While the NeXTStep PS/2 bug is known from QEMU 0.7.0 (which used Bochs BIOS), the other ones are new (as far as I know) so they may be or may not be caused by SeaBIOS.
