I've been experiencing a similar problem.  I'm installing from a 6.2 Release CD to an Abit fp-in9 sli board (nvidia nforce mcp51 disk controller and nvidia nforce mcp13 network adapter), 2 gig ddr2 ram, sata 300 disk.  The install goes without problems but after rebooting, the onboard nic is not active.  "nve0: failed to start NVIDIA Hardware interface".  I add an fxp card, at this point 6.2 release is installed and functional and the system boots up normally.  I can cvsup ports, install ports and even upgrade xorg with no problems.  Although the xorg meta port (x11-drivers) caused me a little grief.  I can also compile a generic or custom kernel and all is ok.

My problem begins when I cvsup to releng_6 and compile a new kernel.  My most recent cvsup is from yesterday 6-4-2007 although I've been fussing with this board since the middle of May.   After make buildworld and make kernel (GENERIC or custom kernel) I reboot and end up at the "mountroot>" prompt where GEOM tells me that the only device available to boot from is fd0.  But, if I reboot and select Safe Mode the machine comes up without problems and I can finish the steps to building the new kernel.  From then on with each reboot I must select Safe Mode for the machine to come up.  I get the same results whether my disk drive is a single IDE or a single SATA-300.

It would be nice to get things working with this board.  This is my first nvidia chipset board but it looks as though I'll be looking for one with the trusty Intel chipset.
