I don't see why the package management would get in the middle of that.
Because you would then have to fetch and compile any proprietary drivers manually. Not necessarily more work, more a matter of preference.

Just reuse your config file from the boot directory to your kernel directory and compile as is. Obviously, that means you will still have all the unneeded modules but at least you will have working kernel. Then you can tweak it a bit at a time if you feel like it.

Do you mean "compile your own kernel"?

Well, it's a matter of selecting the correct drivers as[*] in menuconfig. There are only two things that you need to boot a system usually: the driver for your chipset so you can access to your HDs, and the driver for the filesystem of your root partition (ext3/2, reiserfs or whatever you use).

The rest can wait, and it's a matter and trying, recompiling and rebooting. Less urgent stuff.

But I really want to learn how to do this correctly
Installing gentoo is a good way to learn the internals of these things. Using the handbook and the manual installation of course, the livedvd graphic installer never worked correctly, and you wouldn't learn anything from that anyway.

This is a good way to get it working quickly

Unhappy 4GB ram 64-bit linux 2.6.27.7

Why does the video driver have anything to do with how much ram is recognized?

I compiled linux 2.6.27.7 from source from http://www.kernel.org/ to my Debian Lenny/Sid distro.
It works fine except, I have 4GB ram and an Intel Core 2 Duo CPU E4600 @ 2.40GHz. But only 2.3 GB of ram shows up.

Why? I compiled a 64-bit AMD64 kernel.

I don't know what those BIOS-e820: lines mean.
