Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

Remember, I am running the RHEL 2.6.9 kernel, not the vanilla one from 
kernel.org. There are numerous patches and backports which have made it 
into the RHEL kernel. I probably wouldn't try running kernel.org 2.6.9 
for anything special. That said, I've not run 2.4 in production for 
three years.

CentOS is a good stable (free) server platform, and there are DRBD 
packages for it. 2.6 is a solid kernel platform, however for production 
vendor kernels are probably a better option - There is a lot less 
variation between two RHEL4 kernels versus 2.6.24 and 2.6.25.

I don't want to start a distro war by any means. I'm just sharing what 
works for me :)
