Hm, would be a shame because I have an XP 2600+. /proc/cpuinfo tells me:

flags: fpu vme de pse tsc msr pae mce cx8 apic sep mtrr mca cmov pat pse36 
mmx fxsr sse syscall mmxext 3dnowext 3dnow ts

...no NX in there. I wonder why this (already applied) patch should do 
anything on my box at all.

Thanks,
