I'm slowly but surely starting to switch to a new laptop. The old one hasn't completely died (yet) but given that I had to force its CPU frequency at the lowest Hz or the CPU would burn (and the system suddenly shut down due to heat issues), and that the connection between the battery and laptop fails (so even new battery didn't help out) so I couldn't use it as a laptop... well, let's say the new laptop is welcome ;-)
Building Gentoo isn't an issue (having only a few hours per day to work on it is) and while I'm at it, I'm also experimenting with EFI (currently still without secure boot, but with EFI) and such. Considering that the Gentoo Handbook needs quite a few updates (and I'm thinking to do more than just small updates) knowing how EFI works is a Good Thing (tm).
For those interested - the EFI stub kernel instructions in the article on the wiki, and also in Greg's wonderful post on booting a self-signed Linux kernel (which I will do later) work pretty well. I didn't try out the "Adding more kernels" section in it, as I need to be able to (sometimes) edit the boot options (which isn't easy to accomplish with EFI stub-supporting kernels afaics). So I installed Gummiboot (and created a wiki article on it).
Lots of things still planned, so little time. But at least building chromium is now a bit faster - instead of 5 hours and 16 minutes, I can now enjoy the newer versions after little less than 40 minutes.
