I don't think your problem is the xetex upgrade.... see below...

This indicates that LaTeX is looking for the Charis font with T2A  
encoding, which doesn't exist; fonts loaded through fontspec use  
encoding "U".

(Same problem for Lucida)

That's probably what is changing the font encoding, and breaking the  
fontspec fonts. I know little about Babel and nothing about KOMA  
(what's that?), but in general packages designed to support non-Latin  
text in pre-Unicode TeX systems are not going to work very smoothly  
with xetex and Unicode fonts, as they assume the use of other  
(usually non-standard) input and font encodings. For xetex, that's  
largely unnecessary (and actually interferes with simple operation).

....in Russian, but (I'm guessing) not in fonts you've requested via  
fontspec, but rather some legacy fonts chosen for you by the Russian  
package you're loading.

Right, this is not at all the same issue as Yves ran into.

This warning appears because 10.4 doesn't like the font format we're  
using to get old .pfb PostScript fonts (e.g., Computer Modern, etc)  
into the PDFs that xetex (actually xdv2pdf) generates. It's annoying  
but seems to be harmless.

I don't know enough about Babel, and its Russian support in  
particular, to give a definite answer, but perhaps the notes above  
will point you or others in the right direction.
