Just to clarify, I meant a guest Linux kernel above. And you are trying
to run solaris as a guest?

Hm. It takes some time before the Linux kernel starts outputting things
on the serial port. It has to decompress the kernel etc.

I have created a little Linux distribution designed to run within QEMU,
it is using the -nographic mode successfully. If it would be helpful to
you I would be happy to send a binary tarball via email (~3 MiB large
binary tarball, ~95 MiB tarball with sources).  

Or if someone knows a good bittorrent tracker for free software then I
would be very happy to seed it.

Good Luck!
