Well I already brought this wiki page up on here, but nobody really
cared about updating this.
I even did the same as you updateing that patch to current SVN ;)

Thanks that at least you try to that GDB + Qemu stuff easier.

Even with the patches from Lubomir from May I wasn't able to get the
symbols of the loaded modules.
I have used that load_modules function which is in the new gdb-macro
patch but it didn't work.
And the gdb-stub didn't apply and I was unsure if it was safe to just
adjust the values in the header file which was changed.

I think I'm not that good in this stuff to get it working, so it's very
nice that you want to do it now :)
