50efc3b8c7 - apply Conn Clark's patch.perf-regparm-cclark : 
- it works only on x86 with gcc2.95+
  - uses the GCC function atribute "regparm(n)" to declare that certain
    functions use the register calling convention
  - performance improvement is about 6%

b77b477bfa The PIT is going to start using virtual timers instead 
of having its own realtime mechanism.  The old PIT
realtime mechanism will be removed next.

4ea5f058f5 This is a hideously ugly hack that removes some of the

e492acd792 - VBE 4 bpp modes are using the default vga read/write/update code (for VESA 
mode 0x102 = SVGA mode 0x6a)
- function redraw_area() now uses the old screen dimensions for redrawing

f25a3df39b - added minimal USB support (patch from Ben Lunt <fys@cybertrails.com>, updated 
and improved by Christophe Bothamy and Volker Ruppert)

Comment from the author:

Attached is a "patch" file detailing what you need to do
to add USB support (UHCI only for now) to your existing
Bochs (2.0.xx) source code.

I use Win32 and VC++ but the source and modifications
should be platform and compiler independant.

Please let me know if this patch some how breaks the
build process of your compilation (Bochs 2.0.0 or above
only).

I would also like any feedback on how this code works
(or doesn't work) on your platform and within your
images. If you explain in as much detail as you can on
how it did or did not work, I will try to add to the source
to help it work on all platforms and images.

712af448b4 - add a default #else case when include system specific includes and defining BX_CD_FRAMESIZE. 
This should fix the compile problems on Irix and Tru64.
  I'd like to backport those changes to 2.0.2, when I'll be confirmed it works ok.

    booting the DLX linux demo)
  * force a redraw of the screen in text mode
