[ale] SMP problems with Tyan Tiger MB

[Chris Woodfield]

A minor nitpick - steppings had nothing to do with a rate for  
anything - the term "stepping" refers to internal revisions of the  
same cpu model, generally done to fix microcode bugs or to increase  
production yields.

Intel used to have stepping compatibility charts on their website,  
but I can't seem to find them now.
