ebd7fc5099 Make sure ACPI structures are byte-aligned 
Apparently, guests are very tolerant of corrupt ACPI tables because our 
tables have been badly corrupted for some time now.  A version of 
Knoppix using a 2.6.11 kernel refused to boot and it turned out it was 
due to the interrupt override table introduced by the recent HPET 
commit.

This patch updates the BIOS and introduces a patch to pack the ACPI 
tables.  If you have a guest that used to work and is broken by the this 
commit, let me know.  We have some weird hacks in the tables that I 
suspect are work arounds for this bug.

16b29ae180 Add HPET emulation to qemu (Beth Kon) 
This patch adds HPET emulation.  It can be disabled with -disable-hpet.  An hpet
provides a more finely granular clocksource than otherwise available on PC.
This means that latency-dependent applications (e.g. multimedia) will generally
be smoother when using the HPET.

ca7b25e3ab Update to the latest Bochs BIOS 
Update the PC BIOS to the latest version, split out the patches into 
patch series, and update the README to point to the new location of the 
Bochs BIOS source tree.

Also update the gitignore to allow the patch queue directory to be used.
