Comment (by kvark):

 I'm going to work on a patch that adds the following check box to the
 fail-safe video modes list in the boot menu:
 "Prefer additional VESA mode, if provided", checked by default.

 In case of my setup, that would be exactly 1366x768 that I need:
 KERN: Additional Video Mode (1366x768@59Hz):
 601     KERN: clock=72.33 MHz
 602     KERN: h: (1366, 1414, 1446, 1526)
 603     KERN: v: (768, 770, 775, 790)

 It is going to be a workaround, which would at least allow me to work on
 Haiku comfortably, including finding the solution for radeonhd
