[RFC] Moving Intrepid to 2.6.27 kernel

[Daniel J Blueman]

For the nVidia case, the current drivers (177.13?) are reported to run
fine with the patch posted at:

http://www.nvnews.net/vbulletin/showthread.php?s=b3115cae722ae4537b9d81cf26810ba0&t=117209&page=2

In another case, there is an ALSA patch in 2.6.27-rc4 which enables
recording (thus skype) on my ALC883 audio chipset and motherboard,
which is non-functional in all previous kernels; we should anticipate
additional work and risk in _backporting_ such fixes, if we stick to
2.6.26.

A good example of such risk, is the NFS oopsing issues we still
haven't yet addressed in Hardy with patches we need to backport from
2.6.25, but I'm working on it ;-) .
