Problem with mod_fcgid on AMD64

Earlier today I reinstalled one of our web servers (Dell PowerEdge 860 
running dual or quad core Xeons) with amd64 RELENG_7 as of today, 
replacing i386 RELENG_7 from about a month back (clean install).
After installing Apache 2.2.9 and mod_fcgid 2.2 from ports exactly as on 
the other i386 machines, Apache fails to start with:

[Sat Sep 06 19:48:19 2008] [notice] suEXEC mechanism enabled (wrapper: 
[Sat Sep 06 19:48:19 2008] [emerg] (12)Cannot allocate memory: 
mod_fcgid: Can't create share memory for size %zu byte

The only information I can find on the web relating to this error 
suggests (on Linux) adding a SharememPath config option to httpd.conf, 
but setting this makes no difference. A zero byte file is created, and 
that's it.

The exact same configuration works fine with i386. Is it possible there 
is some incompatibility with amd64?
