Xorg.0.log with driver from git and --enable-debug=full
https://dl.dropboxusercontent.com/u/42927427/Xorg.tar.bz2

My actions:
started kde
started Konsole
ran dmesg
spent about 10 sec moving scroll bar up and down
swiched VT and killed Xorg

weird thing is that scrolling Konsole with --enable-debug=full was little bit
faster. and it was only thing that was faster - other things are slow as hell.


P.S.: commit
http://cgit.freedesktop.org/xorg/driver/xf86-video-intel/commit/?id=cb35b397395cff8ff7f5155759f58c1840bfeeb5
breaks compiling with --enable-debug=full
with error: sna_display.c:3176:43: error: 'struct <anonymous>' has no member
named 'rotation'
     assert(cursor->rotation != sna->cursor.rotation);
so i had to rollback this one
