I don't know much about the status of the Alpha port - I don't think
anybody is currently working very hard on it at the moment (at least, I
haven't seen too many patches lately).

If it's failing regression tests, that's probably where you want to
start.  Try to isolate where the problems are occuring.  eg. Build a
kaffe that works on x86, and one that doesn't on Alpha, and turn up the
verbose options to see where they diverge.  Then try using gdb or
printf's to zoom in even further.  You'll probably have to do some
reading to try to understand what the bits are supposed to be doing, and
then try to figure out where they are going wrong (unfortunately, our
docs are currently a bit weak).  It can get really icky if it involves
toolchain/compiler issues (but it's definitely interesting if you like

Okay.  Possibly it might have something to do with the compiler
re-ordering the symbols (see the "-O4 jit3 problem" thread from the last
few months).

Good luck.
