Hi, again. I've forgot to mention that I had vm.pmap.pg_ps_enabled enabled. So, I've tr= ied various combinations of hw.physmem and vm.pmap.pg_ps_enabled. No valuabl= e result, only a bit smoother graphics with the superpages disabled. So I th= ink there is no reason possibly to continue testing various settings, becaus= e I have a bit customized setup: a bit customized kernel; xf86-video-intel, l= ibdrm compiled with gcc45, not the system default one... And each can be the= cause of such behavior. So, I consider upgrading to amd64. But... If you yo= u have any more recipes to try with i386 system, I'll try them.
