Thanks very much for pointing this out. I'll update the tarball  
shortly. I must have broken the emulator port while working on the  
Dream port.

Your compiler should be fine. I had to compile my own toolchain  
because I use a Mac, and doing anything with GNU libc on a Mac is very  
painful. :-)

You're right about the chip type. The goldfish machine description  
(platform/goldfish/tools/machines.py) uses the arm926ejs chip, so as  
long as your port does the same you should be fine. I just used pxa  
because when I was doing the port (which was a while ago) the pxa  
platform was a little more up-to-date and easier to read. None of the  
actual code from the PXA port gets used anywhere else, so machines.py  
should be the only important file.

Good luck!
