When I installed my system back in January, I started off with 64 bit only, and immediately hit a problem with grub compilation. I switched to multilib, and the installation went smoothly. I would recommend Pappy's seeds as a starting point for kernel configuration. Even if you don't use his seed, the debian resource to identify drivers is useful. If you need a link, I'll sort it out when I get home. I have not had any issues with the multilib setup, and compared to my old AthlonXP system it flies!

Rgds.,
Paul

Didn't you post on gentoo-user that you watch youtube videos? Well, the
currently stable version of adobe-flash (10.1.102.64) is 32bit-only.
That will change again with the next higher version in the tree but the
switch to 32bit can happen again when Adobe decides once again that it
doesn't need to fix its security bugs for amd64.

You might also want to think about pre-compiled OSS applications in
portage (`eix -- -bin`). Not all of them come in pure 64bit flavor.

AFAIK there are only two reasons to avoid a multilib setup:
1. Disk space (~230MB on my system)
2. Compile time on packages that support multilib.

I don't think either of these will be an issue for your new system ;)
IMHO the increased flexibility is well worth the effort.

Hope this helps,
Florian Philipp
