Linux PXES thin client setup

I've recently begun working on using the PXES Universal thin client software from sourceforge.  This is an extremely interesting project and I've enjoyed figuring it out.  Currently I have a ramdisk and kernel that I can boot with via tftp.  However, when I take that same image and install it locally it crashes in a kernel panic.  I've included the last few lines of the boot process with this message.  As far as I can tell either I need to change the limit in the ramdisk or set the device that root needs to boot from.  I would appreciate and suggestion anyone may have.  Thanks in advance.

Hi,

   What's your boot option for "root=" in your boot loader (grub or lilo)
Such as:
----
pxelinux.cfg/vmlinuz-2.4.9-31 ip=dhcp root=/dev/nfs nfsroot=<NFS server>:/<path to boot image>
----

Actually, I increased the size of the RAM disk and the problem went away.
