qnx 6.4 on qemu

I tried to start qnx 6.4 on qemu but i got a problem due to usb mouse. It does not work when the Photon gui appears, but i can use keyboard to login.
In a normal boot process it show me: “Can’t locate PNP bios (No error)”. If i set some boot parameters like “pci-bios, waitfor /dev/pci”, the mouse works fine but now the keymaps appears to be totally wrong. Anybody knows how to solve this problem?

at ubuntu 8.10 - starting…

qemu -hda qnximage -k en-us
boot process/F4 : pci-bios, waitfor /dev/pci
