It's entirely unclear what "re-test" here means, unless maybe by 
incorporating your immediately preceding thread response. Current behavior of 
Grub2 menu overall and first grub.cfg stanza is acceptable having used/using 
the following:

http://fm.no-ip.com/Tmp/Linux/Mdv/menu.lst.04-cldrn-gx27b.txt

http://fm.no-ip.com/Tmp/Linux/Mdv/etc-default-grub-cldrn-gx27b.txt

http://fm.no-ip.com/Tmp/Linux/Mdv/grub.cfg.06-cldrn-gx27b.txt

Only error message I recall is about vga= from Grub2 before first kernel/init 
messages appear.
