+Disclaimer: alphas under my command have never run X and are least likely to 
+suddenly start running it anytime soon.
+
+        Alpha used to have some ridiculously low amount of shared memory
+configured. 
+So quite a lot of apps used to barf. Namely - cdrecord, mysql server, etc.
+
+        Check where is yours at the moment and raise it to a more appropriate
+value by either catting to the appropriate /proc entry or changing the
+/usr/src/linux/include/asm/shmparam.h.
+
+        Otherwise the shared memory on alpha should be fully functional and I
+see no reason to disable it. Mine are bumped up to 32 or more on most
+machines.
+
+        And If I recall correctly the comments in that file are actually
+wrong. Value is not bytes, but in machine size word. For alpha *8.
+
+        As I said - I do not run X on them so all #include "stdisclaimer.h"
+apply.
