Hi Merkur,
you are completely right, but for example if you want to use the zaptel driver for asterisk, actually I have this one zaptel-modules-2.6.27-14-generic, and I think that this will not be working post upgrade.
Actually I don't know how many packages are completely depending on the 2.6.27-14 kernel.
Sure for one of mine DVB card I need to recompile the linuxtv drivers but I'd already do it.
Thats all
Luke
