Most likely.  But in my experience normal 2D dekstop usage doesn't 
go any faster using the via instead of the vesa driver.  (But this 
is with an Athlon processor, not a VIA one.)

Yes, that would be nice; attach it to the bug you'll post.

Better use http://www.openchrome.org/trac and choose New Ticket.

It's unmaintained.  The Mesa-6.4.2 version works fine on KM400 and 
similar, but most 800 chips have problems: the routines haven't 
been adapted for them.

Be more specific.  Maybe you're referring to:
https://bugs.freedesktop.org/show_bug.cgi?id=5092

That's probably the transparency thing?  If you switch off AIGLX 
does the message go away?

Section "ServerFlags"
        Option          "AIGLX" "off"
	...
EndSection

About not getting an answer: it may be because you're asking many 
questions in a single email.  It's better to handle one issue per 
mail.  And in that case use a specific subject line.
