Daniel,

I use these options in my kernel for 1GB:

options         MAXDSIZ="(1024*1024*1024)"
options         MAXSSIZ="(1024*1024*1024)"
options         DFLDSIZ="(1024*1024*1024)"

See 
http://lists.freebsd.org/pipermail/freebsd-questions/2004-August/056890.html

I tried with ulimit -d 2097152, but when I check back again (immediately after setting it), it reads "data seg size           (kbytes, -d) 524288" (again).  I tried changing kern.maxdsiz, but I get "sysctl: unknown oid 'kern.maxdsiz'"... I'm running 6-STABLE as of two days ago.
