Yes, a similar one, except that the kernel panic did somehow mention  
the code I quoted above.

I have seen it both in 0.9.0 and in 0.9.0 + HEAD openbios-sparc32 on  
OS X Intel.
But I am unable to try CVS HEAD there because some of Q's patches do  
not work against HEAD. Would be great if they could make it into CVS  
to avoid these issues.

I also made some local changes to tcx.c today to avoid having a blue- 
footed penguin on Intel. There's a TODO in that file saying the RGB  
functions should be merged with vga.c (where they are being patched  
by Q) - should I provide a qemu patch doing this and fixing the issue  
for both? Or is this for some reason restricted to Q?

On PPC I wasn't able to follow an identical installation path and the  
point of error on Intel was pretty much reproducable, so I can't tell  
whether it would have surfaced later on. From my view these are two  
separate issues, and for now I can only test the network issue on ppc  
- unless someone has instructions how to correctly patch HEAD for  
Intel support...
