xorg and framebuffer issues with high resolutions
So I got a nice shiny new 23" 1080p Asus VH236H monitor. Unfortunately, it's not turning out to be as great I was hoping, possibly due to the Geforce FX5200 bios, but I'm not sure. I think these issues are probably related, so I put them in the same thread.
First, the console: vesafb, uvesafb, and nvidiafb all fail at delivering a useable framebuffer greater than 1280x1024. vesafb flat out denies anything beyond 795 (0x31B). uvesafb and nvidiafb will fall back on 1280x1024@75Hz, which causes text to flash all over the screen and requires a reboot to remedy. It doesn't matter if I feed fbset the exact timings X uses, they'll still fallback on 1280x1024. hwinfo has this to say about hardware support:

Supposedly, the framebuffer should be able to support 1400x1050, but I can't get it, possibly because it's not listed as monitor supported. Does this mean that I'm stuck with a 1280x1024 max res?
This brings me to my next problem... Xorg. On my old monitor, I liked the nvidiafb-fbdev driver combination because I could quickly switch between X and console, and so long as I had the proprietary nvidia gl libraries installed, X ran smoothly. (never got the nv driver fbdev option to function with stability) Obviously, this is impossible now. I can't get nv to run at a resolution greater than 1280x1024. With the proprietary drivers, max resolution is 1440x900; however, if I disable max pixel clock checking, support for 1680x1050 and 1920x1080 is added.
Now, this is where things get serious. If I switch back to console after starting X with NoMaxPClkCheck, I get an out of range message from my monitor. I can freely restart/switch back to X and everything is fine there, but the console is unuseable until reboot.
