Ok ny kerne: redhats 2.4.18-18.7.x.

Den kerne er OK; redhat har backportet nogle patches til denne kerne. Mht. DMA support kan du teste vha. hdparm.

# hdparm -t -T /dev/hda

På min flunkende nye 2.3 GHz IBM M42 maskine gav den
2-3 Mbytes/sek på en standard Mandrake 9.0 kerne,
og ca. 40 Mbytes/sek på en RedHat 8.0 kerne (eller
en nyere 2.4.20pre10 standardkerne). Lidt af en forskel...

Gør det, at agpgart nu er loadet, en forskel mht. X's
RAM forbrug? agpgart skal selvfølgelig loades før X starter...

Nu har jeg ikke så mange erfaringer mht. NVidias drivere,
så jeg ved ikke hvordan den har det mht. agpgart.
