There is a potential for a mismatch between kernel and Xserver. The mismatch
occurs in the area of the MIT-SHM extension of the server, but only comes
into play when an application wishes to use certain facilities (Quake wants
to setup a SHM area between it and the server; if the server's SHM data
structures don't match those of the kernel's SHM, a problem occurs).

Working combinations, as per my previous mail on this subject, are:

1. ECOFF Xservers and linux kernels WITHOUT the axp-diffs

2. ELF Xservers and linux kernels WITH the axp-diffs

(The mismatch is actually between GLIBC used by the ELF Xservers, and the
stock linux kernels).

I believe (somebody please correct me if wrong), that the 2.0.xx kernels
must be patched with the axp-diffs, but the 2.1.xx do not????

And I also believe (again, please correct) that the Red Hat kernel RPM
doesn't have the axp-diffs that fix the problem; that occurred with later
axp-diffs (2.0.21?).
