The i810fb driver and the XFree86 i810 driver appear to be incompatible,
because the former likely holds open the agpgart driver, which the latter
needs:
(WW) xf86AcquireGART: AGPIOC_ACQUIRE failed (Device or resource busy)
(EE) GARTInit: AGPIOC_INFO failed (Invalid argument)
(EE) I810(0): AGP GART support is not available. Make sure your kernel has
agpgart support or that the agpgart kernel module is loaded.
I'm not sure how using the i810fb driver with the XFree86 i810 driver would
get you dynamic rotation anyway.

The XFree86 fbdev driver is designed to interface with the the fb module
you load into the kernel, in this case i810fb, so that is expected to work.
