[PATCH][2.6] Dont use cpu_has_pse for WP test branch

[Zwane Mwaikambo]

It appears that not all processors which support PSE have the PSE bit set, 
possibly we should be checking with PSE36 too. But instead i've opted to 
simply check for 586+

Celeron (Mendocino): fpu vme de tsc msr pae mce cx8 apic sep mtrr pge mca 
cmov pat pse36 mmx fxsr

Opteron 240: fpu vme de tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat 
pse36 clflush mmx fxsr sse sse2 syscall mmxext lm 3dnowext 3dnow
