Patch1950: linux-2.6.9-agp-missing-cacheflushes.patch
Patch1951: linux-2.6.9-agp-posting-bugs.patch

upgrading from kernel 1021 to 1032 broke Xen.  System hard locks after
agpgart message.

Removing patch #1051 did not resolve the problem but removing #1051
and #1050 did resolve the problem.  #1051 does not apply clean without
#1050 and was not tested on its own.

440BX/ZX/DX - 82443BX/ZX/DX host bridge
82371 AG/DB/MB  chipset.
NM2360 video.

No serial port on this machine but the last messages with kernel build
1032 Xen0 as delivered are:

agpgart:  Detected an Intel 440BX Chipset.
agpgart:  Maximum main memory to use for agp memory:  96M
*hard lock*

Kernel build 1021 continues with:

agpgart: unable to get memory for graphics translation table
agpgart: agp_backend_initialize() failed.
agpgart-intel:  probe of 0000:00:00.0 failed with error -12

The boot completes and the system is usable on console.

Removing patches #1050 and #1051 from 1032 returns xen0 to a usable
state as observed with build 1021.
