Thanks, I downloaded the 9pi file (~2MB, MD5 -
4e4e18980d8ac91b0e8ed5aa820dc429) from contrib/bakul directory.

I could boot the R-Pi with this kernel and get the kb and mouse
working fine! Thanks a lot to everyone! One of the mice I had (a very
cheap, small mouse) didn't work though. Nevertheless, I am very happy
that it is all working now and have something to play with.

A big thanks again.
