Look for the series starting with

[PATCH 0/2] drm/nouveau: add support for 2560x1440 at 56 over HDMI

sent to nouveau and dri-devel on Aug 8. It limits things to 225mhz though. We
did some poking around with various VBIOS's, I think I found the place where
the max freq is stored, but would be curious to see yours (can be grabbed from
/sys/kernel/debug/dri/0/vbios.rom).
