SATA на чипсете SB600, uvesafb с highmem64g

Обновил железо...
1. Не могу подцепить sata винт. Контроллер SB600. Перевёл в Ahci. Вкомпилил поддержку в ядро. Вывод dmesg:

2. Проблема с uvesafb. На борту 4гб DDR2 PC2-6400. При включении в ядро CONFIG_HIGHMEM64G в буте пишет:

uvesafb: Getting VDE info block failed (eax=0x4f00, err=1)
uvesafb: vbe_init() failed with -22

Соответственно при переводе её в режим 4G всё ок, если не считать утечку 1гб рама,,,

3. Не пойми с чего во время бута пишет
PCI: Cannot allocate resource region 3 of device 0000:00:00:0
конечно не мешает, но всё же.
