[gr0x0rd <312756@xxxxxxxxxxxxxxxxxx>]

Proud (?) owner of a brand new Asus N53JF.

Gentoo user but in the same boat as all of you. Currently running
2.6.34-gentoo-r12. Have yet to get the discrete nvidia GeForce GT 425M
working in X, been running the integrated intel chip so far. Have tried
the 256.53, 260.19.21 and 260.19.29 binary drivers with a xorg.conf
generated by nvidia-xconfig (but had to add BusID field to the Device
section for the card to get the driver to find it) without success. I
have submitted a bug report to nvidia regarding the issue. The latest
unmasked version of the nouveau driver in portage does not recognize the
card.
