Yes, I'm running 32 bit host and guest. I have no custom kernels - so my 
FC6 guest and my RHEL5 host and guest are all stock distro kernels.

Does this still apply then?

BTW: I am also running a 32 bit FC3 guest (2.6.10-1.770) with openafs 
1.4.1, and I am now putting all my write I/O through it (and it hasnt 
missed a beat)...

If I get a chance, I'll upgrade it slowly to see if this is a 1.4.2 
problem, or a later kernel problem...
