Hi rusty, 

IIRC, I got the same error when I ran lguest out of a pretty old mm kernel 
(2.6.24 rc5-mm/rc4-mm). I imagined it to be a usual problem with the mm 
kernels itself and didnt bother report it. I also remember seeing a message 
in dmesg which told me to pass a large enough number to vmalloc=XXX kernel 
parameter for the module load to succeed.


I don't remember the exact details, but I thought i should report whatever i 
remember..
