New kernel broke xserver (can't open socket)

[steve doerr <sdoerr@qni.com>]

After going from kernel 2.0.36 to 2.2.0 I can't get a socket for
the xserver.  Has anyone seen an error like this?  Did I miss something when I built the kernel?

The server reports the following (excerpts):

"_XSERVTransSocketOpen: socket() failed for local
_XSERVTransSocketOpenCOTSServer: Unable to open socket for local
_XSERVTransOpen: transport open failed for local/debian:0
_XSERVTransMakeAllCOTSServerListeners: failed to open listener for
local"

"Operating System: Linux 2.0.36 i686 [ELF]"  (the old  kernel)

Any help greatly appreciated!
Thanks,
Steve
