[gentoo-user] GRUB speed up

I've noticed that GRUB takes a rather long time to start up on my 
computer. Granted, this is PII 550 Mhz. But it takes several seconds 
just for GRUB, not for anything to do with the kernel starting. The 
attached file is, obviously, my configuration file. BTW, the commented 
out entries are just old.

Any optimization ideas out there?

Yes, try to kick out the Splashimage... I think there's not much more,
you can do...

title Linux 2.6.11-gentoo-r8
    root (hd0,3)
    kernel /kernel-2.6.11-gentoo-r8 init="/linuxrc" root=/dev/ram0 
real_root=/dev/hda1 video=vesafb:ywrap,mtrr,1280x1024-16@85 udev

Grub reads the data into ram as soon as it reads the kernel or initrd 
line. The time it seems to wait, is the time required to load this into 
ram. Since grub uses (i assume) bios calls, reading with those is much 
slower than disk access through the modern os drivers. 

I'd check for the size of the initrd, and see if its compressed. It 
seems to lack the .gz extension so it might not be.
