This is worth forwarding to SYSLINUX.

Which RAID level are you using?  I think RAID-0 and RAID-1 should work
fine - the bootloader does not need to be aware.  I don't know how
booting from the other RAID levels is supposed to work.

Perhaps the PXELINUX in your gpxelinux.0 and CentOS pxelinux.0 are of
different versions.  To determine for sure whether gPXE is involved in
this issue, please build gpxelinux.0 and pxelinux.0 from the same
SYSLINUX source tree.
