Trouble booting new kernel, can't find VolGroup00

I've successfully installed Fedora 5 on my home machine and I just
completed a fresh kernel compile (need a few drivers). I left all
the LVM/RAID stuff turned on but turned off various things I didn't
need (stuff for laptops, etc). Now when I boot the machine with
the new kernel I get:

Red Hat nash version 5.0.32 starting
  Reading all physical volumes.  This may take a while...
  No volume groups found
  Unable to find volume group "VolGroup00"
Unable to access resume device (/dev/VolGroup00/LogVol01)
mount: could not find filesystem '/dev/root'

I basically copied the working grub entry except for the kernel
and initrd file name (the original kernel still works fine). Here's
the new entry:

title Fedora Customer kernel (2.6.15-2.2054 FC5)
	root (hd0,0)

	initrd /initrd-2.6.15-2.2054_FC5

Sorry about the wrap. I must be missing some step after I compile,
install the new kernel.rpm and mkinitrd in boot but I can't figure
it out yet.

Thanks
