I have worked around this temporarily with the following patch:

Hi Fabrice,

    I have managed to download the latest cvs and tried it out on Fedora Core 3 (kernel 2.6.10).  It seems that for some reason the kqemu module is unable to be assigned major device number 254.  Below are the errors:
address@hidden ~]# modprobe kqemu
FATAL: Error inserting kqemu (/lib/modules/2.6.10-1.760_FC3/misc/kqemu.ko): Device or resource busy
