Log message:
add a new getparam member to get the contents of scratch register 3 (the
one we use to dump the software interrupt number).
For some strange reason noticed upstream, writeback doesn't seem to be
working for this value for use, so instad of using the get_scratch
functions, we fallback to a direct register read (more bus traffic, but
it actually works).
This is to be used by new mesa on r100 and r200 since they reworked
stuff for dri2, and we have local patches that prevent userland mapping
the registers in dri clients.
Tested by Josh Elsasser on a M9 (rv250), thanks very much to him.
