Problem med Xorg

Heysa gutter.

Jeg har mit mediecenter herhjemme hvor jeg har kørt med ArchLinux som OS i meget lang tid.
Jeg har løbende opdateret mit system, inl maskiner mm.,
Jeg er endt op med nogle ASUS EEE B202 som frontends i mit system.

Men efter en kernelopdatering er jeg rendt ind i nogle xorg problemer jeg ikke helt forstår og ved lige hvad jeg skal gøre ved.
Efter at have set TV i noget tid uden nogle former for problemer - så går min skærm i sort/blank og kan ikke komme tilbage til alm. visning mm man rebooter.
Min dmesg kommer til at se således ud imens det sker:

Er der nogle der kan fortælle mig hvad der konkret sker - netop fordi det er kun på mine ASUS EEE B202 hvor dette sker - og ikke på mine shuttler. Derfor er det noget underligt - og lige dette problem aner jeg ikke meget om.

jeg har også spurgt på Archlinux.org men intet svar.
Jeg ved ikke lige andet end hvad der står - men ikke hvad jeg skal gøre for at afhjælpe dette.
Selve memory burde vel ikke være et problem, men 1GB RAM og 2GB SWAP.
Min top mm når og inden det sker viser omkrin 20% us på CPU.
Omkring 600mb RAM brugt og intet i swap.

Hvorfor skærmen bare bliver sort - kan jeg kun se på selve skærmen og i xorg.0.log:
