You can use modelines, but I don't have patches for Linux, so the pixel clock is limited to 330 MHz.

This should work for 2560x1440 @ 85 Hz:

Modeline "2560x1440_85" 329.90 2560 2608 2640 2684 1440 1442 1444 1446 +HSync -VSync

Modelines are structured like this:

"Name"
Pixel clock
Horizontal active
Horizontal active + front porch
Horizontal active + front porch + sync width
Horizontal total
Vertical active
Vertical active + front porch
Vertical active + front porch + sync width
Vertical total
Flags like +HSync/-HSync and +VSync/-VSync for sync polarity
