I don't think that's correct.

Output from my 32 bit Xeon:
michael@ratty:~$ grep flags /proc/cpuinfo
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge
mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe lm
constant_tsc pni monitor ds_cpl cid cx16 xtpr
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge
mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe lm
constant_tsc pni monitor ds_cpl cid cx16 xtpr

has 'lm' 

So I'm unsure what's happening here!
