 Not able to give you the exact error but the problem is with an = after
 title, so this breaks:
 default=0
 timeout=5
 title=Red Hat Enterprise Linux Server (2.6.18-194.17.4.el5xen)
         root (hd0)
         kernel /boot/vmlinuz-2.6.18-194.17.4.el5xen ro console=hvc0
 root=/dev/xvda1 audit=1
         initrd /boot/initrd-2.6.18-194.17.4.el5xen.img

 This works:
 default=0
 timeout=5
 title Red Hat Enterprise Linux Server (2.6.18-194.17.4.el5xen)
         root (hd0)
         kernel /boot/vmlinuz-2.6.18-194.17.4.el5xen ro console=hvc0
 root=/dev/xvda1 audit=1
         initrd /boot/initrd-2.6.18-194.17.4.el5xen.img

 Now the grub manual says that it is supposed to be title with a space
 after it and the first non white space character is used as the actual
 title, however it appears that both a space and an = will work.

 So if I were to guess, and god knows I am because I don't know squat about
 your lense syntax I would say this line needs to be changed.
 From:
 let title = del /title[ \t]+/ "title " . value_to_eol . eol
 to:
 let title = del /title[ \t=]+/ "title " . value_to_eol . eol

 And it appears to work for me (tm).

 So here is the patch:
