-rX is an internal Gentoo release number.  But with the kernel, you'll 
note that they don't normally track the upstream 4th level release 
numbers, so that ends up getting wrapped into the -rX number as well.

Do note however that they don't necessarily exactly correspond.  Thus, 
2.6.30-r1 may or may not correspond to upstream's 2.6.30.1.  Generally, 
there will be bumps about the same time, but if Gentoo finds and patches 
other issues between upstream bumps, it might bump the -rX twice for a 
single upstream 2.6.x.y bump, and the reverse occurs as well.  
Occasionally there'll be an upstream bump, and then another one maybe two 
hours later the same day, if they found a brown-paper-bag issue (in LKML 
lingo, a really embarrassing mistake, such that one wishes to cover their 
head with a bag if they appear in public immediately thereafter), or if 
there's an exceedingly urgent but also exceedingly simple security fix.  
These would probably be wrapped into the same Gentoo -rX bump.
