[Gpm] Question: GPM + SVGATextMode at 132X60 problems

[Dew-Jones, Malcolm ISTA:EX]

Hello...

(I wonder if this will even get on a list and if so, whether i will be able 
to see a reply)

I'm trying to use GPM in combination with SVGATextMode at 132x60 screen
size.

GPM works fine at the default 25x80 screen size, but not at the larger size.
Sometimes I see a large rectangle covering 10 lines or so if I bash the 
mouse(!) but even that is not reliable.

Questions: 
1 Any suggests on what's wrong or how to fix it.
2 Where do I find the source code (The man page mentions prosa.it, but I 
  don't see how to get GPM stuff from there).

Any help appreciated.  If I need to send mail somewhere else I will happily 
do that too, just let me know what I have to do and I'll do it.
