Hi Rafael. MCP79 is a pretty common chipset, and support is mostly
good (I have it on a Macbook 5,1 and on a mini-itx board and it works
fine on both). However, some variations still aren't well supported,
but work is ongoing.
I suggest you to give a try to the kernel26-rc package on the aur:
2.6.35-rc4 is a very stable release, and reading the shortlog I found
a commit that may be helpful at least for your second issue:
