So I tried recently released driver AMD Catalyst 3.4. tried in both w/ & w/o nomodeset.
Good news are:
Now it supports 3.7 and 3.8 kernels out of box, and one not need to sniff over internet for weird fglrx-3.8.patch in order to build it.
No X crashes so far(but I spent no so much time testing to be sure).
Despite of bugfixes, it still cannot return back to framebuffer console after starting X. Now, when switch to console it partially correctly guesses videomode. If I saw green rectangles before, now I partially can see and recognize text: it looks like it switched to wrong X resolution, multiplied by 2 of that it thinks. Now I see 2 column screen, columns show equal picture. But even those picture is not correct. They looks like stripes, i.e. every even row is black(clear). And last glitch, probably caused by two first is columns are to high. I see only first 1/3 of picture on my monitor. To read result of my recent command I forced to insert a whole bunch of empty line to cause terminal to scroll.
