I got DHCP/TFTP working great with no problems today. I can PXE Boot memtest off of the server with no problem, so I know there's nothing wrong there.
For some reason, the image I'm trying to boot into just doesn't want to cooperate. I'm completely at a loss for what I can do with this and Googling hasn't helped either. I can't see very much of the scrollback, but the last two (important-looking) lines are this:
No filesystem could mount root, tried: reiserfs ext3 ext4 vfat msdos iso9660 xfs
Kernel panic – not syncing: VFS: Unable to mount root fs on unknown-block(1,0)
pxelinux.cfg/default:
label linux
kernel vmlinuz.2628hr7
append initrd=/initrd.gz init=/init noapic acpi=off raid=noautodetect ramdisk_size=200000 devfs=nomount root=/dev/ram0 rw
The kernel is the exact same kernel that actually runs on the exact same hardware configuration as the machine I'm trying to PXE Boot. Could it be a problem with the PXE Image? Any help would be greatly appreciated.

It's not a kernel problem, but it cannot mount the filesystem. Have you changed the partition table? Does the kernel know where root is (ie maybe 'today' it's /dev/sdb instead of /dev/sda.. I've seen it happening). Also consider:
rw?
