Pencentra 200?

Hi All.
I'm an owner of a Pencentra 200.
Its microprocessor is a 129MHz Toshiba(r) TX3922 MIPS RISC CPU.

So i've prepared a CF with :
netbsd-GENERIC.gz (renamed an ungzipped)

[ A gzipped NetBSD kernel containing code
 for everything supported in this
 release.  This kernel runs on Vr41xx
 and TX3922 CPUs only.

from : ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-3.1/hpcmips/INSTALL.txt]
and
pbsdboot.exe

I have no problem to start pbsdboot.exe (using Oencentra 130 framebuffer
profile), but i have this error:
"Error: mapping interrupt vector failed".

I know that it's a known problem (
http://article.gmane.org/gmane.os.netbsd.ports.hpcmips/2069/match=pencentra),
but is there a solution??

Thanks!
