Is that on Squeezy, Wheezy, other...?

I also started to experience a delay in GRUB2 (wheezy) but in another 
stage: after getting the boot menu, there's a noticeable interval until 
the system starts booting.

Anyway, and back to the topic, I can't see a clear relation between the 
BIOS IDE disk mode (LBA/Large/Auto/CHS...) and a delay to get the GRUB2 
menu because GRUB2 code is supposedly loaded earlier, but it could be 
some sort of BIOS firmware bug :-?
