Can't boot linux on sun blade 2000

[Alexey Nezhdanov <snake@penza-gsm.ru>]

Hello. I've already asked my question on debian-sparc and debian boot 
maillists and got a lot of help but still can't solve the problem entirely.
The problem is (slightly edited minicom log):

=====================That's all. It hangs here.

If I specify init=/bin/sh it attempts to kill init and panics.

If I'm plugging out keyboard or using "real" console or serial port connection 
- it not matters and the problem persists.

I've got some hints about "TTYA not found." in the very beginning but I do not 
know what to tell openboot to use insted (And I fear to experiment to not 
broke openboot - I'm very newbie on sparc but have good experience with 
linux).

Please help or point me to a proper maillist (may-be ultralinux ? ).
