Subsequent messages of the linked Gentoo bug report and the associated
Gentoo forum make it clear: The built packages do not work.
Your patch is the reason for the non-functional video-mach64 driver.
Look at compiler.h what your patch does; the video-mach64 driver needs
inb, inw, inl, outb, outw, outl.
The problem with the xorg server also occurred on the Debian project.
Debian has a patch for xserver-xorg-core 1.12.4 which allows to build
the video-mach64 6.9.1 driver on ia64 (without any modification):
- archived Debian bug#685750
Also relevant for you is the
- archived Debian bug#686152
I assume the patches are also useful for the xorg server 1.13.
I hope it helps.
