I have some trouble booting xen 4 x86_64 on my jetway nf76 board. It has a via nano u2300 cpu and via vx8800 chipset. Xen stops with an error in hvm. As far as i know hvm in the nano 2000 is buggy and should be disabled by the bios. Never the less vme shows in cpuinfo:

Since i am not interested in hvm i changed CONFIG_HVM := y in config/x86_64.mk to n, but that did not make the error disapear. 

The error:
