When I run a depmod -ae -F <System.map> on my resulting installation of OFED 1.3 I get the following error:WARNING: /lib/modules/2.6.18-53.1.14.el5_lustre.1.6.4.55.20080411125046smp/kernel/drivers/infiniband/hw/cxgb3/iw_cxgb3.ko needs unknown symbol dev2t3cdev What I can't seem to figure out is why this symbol is not being exported by kernel/drivers/net/cxgb3/cxgb3.ko.

I believe the cxgb3 module you are looking at in /lib/modules/`uname -r`/kernel/* isn't the one you are building. ofed installs its modules in /lib/modules/`uname -r`/updates/*. The cxgb3 module in /lib/modules/`uname -r`/kernel/* is from your kernel tree I think.
Are you doing a 'make install' from the ofed tree?
Are you using only the ofed tree or are you also using chelsio's TOE kit?
