-as long as you don't try to update the system in the normal Mint manner, and manage the install of applications yourself, it probably won't be a problem..http://www.aspireonekernel.com/
It is probably to do with the repository being used and their kernel changes (sickboy)
--although he indicates kernel 2.6.29
--does he tell you which repository to use or which version of Ubuntu based repository to use, he says anything better than Ubuntu 8.04, or Ubuntu derived for his kernel
So if you opened a terminal on that machine, and..
In terminal, check
--what does it show
Second problem, how will you update mint 7 using that kernel, you can't just use
- sudo apt-get update
- sudo apt-get upgrade
--that will look at mint repositories for updates, and likely fail (kernel mismatches )
