I also tried the patch on an Intel Core i5 and had a similar
experience.  I could get further than before with 64-bit Linux
binaries coming from a 64-bit Linux partition mounted at /emul/linux
and ran with a fake raised kernel version.  Graphical programs
eventually failed because they could not connect to the X server,
complaining about the socket type being wrong for the protocol or
something similar (which I did not figure out how to get around).  But
this was already quite promising, considering that with an unpatched
kernel they just dump core.

On the other hand, as Nicholas Joy said, previously working 32-bit
binaries stop working and just use 100% cpu with his patch.

Thanks,
