Trouble booting NFS root

I hope you didnt cut this portion out of your diskless kernel
options  NFS_ROOT # NFS usable as /, requires NFSCLIENT
options         NFSCLIENT               # Network Filesystem Client
options         NFSSERVER               # Network Filesystem Server

You migh also want to re-read FreeBSD Handbook chapter Booting with PXE
(just in case)

and my /var/run/dmesg.boot has these lines instead
+Timecounter "TSC" frequency 1997211896 Hz quality 800
Timecounters tick every 1.000 msec
+IPv6 packet filtering initialized, unlimited logging
+ipfw2 (+ipv6) initialized, divert loadable, rule-based forwarding disabled, default to deny, logging unlimited
+ad0: 76319MB <WDC WD800JB-00ETA0 77.07W77> at ata0-master UDMA100

+Trying to mount root from ufs:/dev/ad4s1a
+rl0: link state changed to UP

so basicaly, may i suggest to ensure that you dont have your firewall cutting off the cord and there is no problems initializing on-board ata devices?

While that is a useful tip, the NFS trace shows that the kernel doesn't 
even try to read any files. The last thing that gets read by anything is 
/etc/fstab, however it seems most likely that fstab was read by the 
bootloader rather than the kernel proper.
