Greetings, ppl.
As far as I can see, geoserver head on svn now contains WMS capable
of doing coordinate transformations. Old LiteRenderer is replaced
with LiteRenderer2. That is really good thing in general, but in my
case it lead to some problems 
My data isn't really in any of EPSG SRSes, it is in non-georeferenced
engineering CRS. With older geotools I simply used "EPSG:0"
everywhere. Hovewer, now this yields an internal error with
"invalid EPSG code" (or something like this) message. I'm not
really surprised to see it 
but I guess there should be some way to
use non-EPSG (more specifically, engineering CRSes) to produce a map.
Remembering David Blasby's recent posts, I think that now I have to
define my own custom CRS somehow and make GeoServer aware of it. The
bad thing I don't really know that much about this stuff (coordinate
reference systems, coordinate conversions/transformations etc.) and
haven't got a time for extensive study of this matter right now.
So it will be really great should someone point me out to any
documentation on defining CRSes and coupling them with geoserver-dev.
If there is a simplier way to get my maps back rendering, it's even
better
