Gentoo on Compaq AlphaServer ES45 Model 2

[trumee]

Hi,
I have finally managed to persuade by boss to go the linux way for our servers. Now the question is that can we get rid of Tru64 OS and install gentoo on it?
The machine details are:

Is it possible to install gentoo on this machine. Can gentoo support the 64bit architecture on these machines?

Thanks for any info.
