the fabulous world of 64 bits II : Xen, Nvidia

So, i successfully passed the Nvidia driver phase. No real problems with the standard amd64 kernel (see below for more...), there's a lot of documentation on the web to use a nvidia graphic card with the proprietaries drivers (don't forget the nvidia-glx package!). The only thing is the dual-head functionnality that i can't really try without a second screen (the KVM output an 'out of frequency' error on the screen on one of the VGA/DVI outputs).

Now, comes the Xen part. It drives me crazy, i rebooted multiple times but i finally found the right combination in my /boot/grub/menu.lst to boot the linux-image-2.6.18-4-xen-amd64 kernel on my ASUStek M2N motherboard. Here it goes: (relevant parts in bold)

title Xen 3.0.3-1-amd64 / Debian GNU/Linux, kernel 2.6.18-4-xen-amd64
root (hd0,0)
kernel /xen-3.0.3-1-amd64.gz noapic
module /vmlinuz-2.6.18-4-xen-amd64 root=/dev/mapper/vg--root-lv--root ro acpi=off noapic nolapic console=tty0
module /initrd.img-2.6.18-4-xen-amd64
savedefault

And finally, the problem comes on the Xen+Nvidia phase. I compiled my kernel modules for Nvidia the same way i did it with the standard kernel, but everytime i launch X (via startx or gdm) the screen turn blank and the pc reboot... with no messages, neither on the screen, neither on my logfiles... i'm a little bit lost, so if anybody got an idea...

so it seems that the solution to my Xen+Nvidia problem is indicated here. As always, my first reflex should be to search here :)
For the moment, the method indicated on the article didn't work for me but i'll check it with more time tomorrow
