James, The 2.5 agpgart code broke the i810fb a while back.
The reason behind this, is that previously (i.e. 2.4) agp_init() would call the chipset specific backend init routines. In 2.5, that stuff got pushed out into seperate modules, so now i810fb does a (superflous) agp_init() which just printk's the agpgart banner, and then calls the intel_agp_init() function directly.
This *should* work, but doesn't.
The agpgart code *absolutely must* be set up before the framebuffer code. Previously this was going to be solved with link order shuffling, however that won't work, as the drivers/video stuff is initialised from drivers/char/mem.c (Really non-intuitive place to hide fb init IMO) mem.c gets linked before agp/ so we lose there.
Hence the explicit init in i810fb. I've tried to untangle this and figure out why that isn't working, at a complete loss. (The lack of hardware to test this on also doesn't help).
Any ideas ?
Dave
