If dmesg is showing 2GB of RAM detected than chances are it's using it
;) 

You'll want to look into some of the sysctl options you can set.  see
man sysctl and sysctl -a 

Some other options may be NMBCLUSTERS, BUFCACHEPERCENT and options
dealing with shared memory see man options. 

Other than that OpenBSD is quite well tuned with just GENERIC.  NOTE: a
custom compiled kernel will basically stop the developers from being
able to help you.  So mess with the sysctl parameters
