NVidia 190.53 working with Xen?

Hi,
Has anyone gotten the NVidia 190.53 drivers to work with Xen?

There isn’t an nvidia-gfxG02-kmp-xen-190.53_2.6.31.8-0.1 package in existance, yet, so I followed the pretty good instructions from Paul for the 185.18 GPL Infringement workaround using the source build and I’m successful making the driver and module, but when I attempt the modprobe nvidia under xen, I get “unknown symbol init_mm” in my dmesg.

I suppose my option might be to go back to 185.18, but I’m hoping that someone has figured this out or made an rpm.

Thanks!
Mike
