Yeah, I did that.

Thanks for the fixes, just tried them out on 32-bit and seems to work
great, will try 64-bit later. I forgot to mention the pkg-config error
when compiling QEMU in the email:

Package lua was not found in the pkg-config search path.
Perhaps you should add the directory containing `lua.pc'
to the PKG_CONFIG_PATH environment variable
No package 'lua' found
Package lua was not found in the pkg-config search path.

to the PKG_CONFIG_PATH environment variable

Error LUA not found, can't build with SerialICE support.

manually doing PKG_CONFIG_PATH=~/lua-5.1.4/etc/;export PKG_CONFIG_PATH
fixes this, but that seems a little odd (and lua-5.1.4/etc/ is the
only location of lua.pc)

Trying the svn version of QEMU now to see if it solves my problem.

Thanks,
Corey
