Hello
Here is a patch that fixes several issues in the agpgart driver :
- The 'cleanup' function for i820 chipsets was incorrectly set to the
generic function (that writes over 16 bits instead of 8)
- Fix incorrect PCI id for the i860 chipset
- Add support for the UP version of i820 chipset
- Config.in update
The patch is against 2.4.15
Best regards
