You MUST make sure that the kernel and Xservers are compiled with the SAME
SHM data structure defs; ie /usr/include/linux/shm.h. Also, ipc.h and msg.h
in the same directory are important as well for other things.

Note that the stock 2.0.3x shm.h does NOT match with the alpha-patches
version (that's the alpha-patches stuff that I put out on gatekeeper). Also
note that the alpha-patches versions of those header files DO match the
stock 2.1.xx kernel versions.

Available for anon FTP on gatekeeper.dec.com:

  /pub/DEC/Linux-Alpha/Kernels/alpha-sources-2.0.35-0.2.tar.gz # prepatched
  /pub/DEC/Linux-Alpha/Kernels/alpha-patches-2.0.35-0.2.gz     # just patches

These are very new (within the last few days) and also fix a number of
little bugs on certain platforms like UX and MIATA.
