Linux-2.6.12-rc2v2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+What is tgafb?
+===============
+
+This is a driver for DECChip 21030 based graphics framebuffers, a.k.a. TGA
+cards, which are usually found in older Digital Alpha systems. The
+following models are supported:
+
+ZLxP-E1 (8bpp, 2 MB VRAM)
+ZLxP-E2 (32bpp, 8 MB VRAM)
+ZLxP-E3 (32bpp, 16 MB VRAM, Zbuffer)
+
+This version is an almost complete rewrite of the code written by Geert
+Uytterhoeven, which was based on the original TGA console code written by
+Jay Estabrook.
+
+Major new features since Linux 2.0.x:
+
+ * Support for multiple resolutions
+ * Support for fixed-frequency and other oddball monitors 
+   (by allowing the video mode to be set at boot time)
+
+User-visible changes since Linux 2.2.x:
+
+ * Sync-on-green is now handled properly
+ * More useful information is printed on bootup
+   (this helps if people run into problems)
+
+This driver does not (yet) support the TGA2 family of framebuffers, so the
+PowerStorm 3D30/4D20 (also known as PBXGB) cards are not supported. These
+can however be used with the standard VGA Text Console driver.
+
+
+Configuration
+=============
+
+You can pass kernel command line options to tgafb with
+`video=tgafb:option1,option2:value2,option3' (multiple options should be
+separated by comma, values are separated from options by `:').
+Accepted options:
+
+font:X    - default font to use. All fonts are supported, including the
+            SUN12x22 font which is very nice at high resolutions.
+
+mode:X    - default video mode. The following video modes are supported:
+            640x480-60, 800x600-56, 640x480-72, 800x600-60, 800x600-72, 
+            1024x768-60, 1152x864-60, 1024x768-70, 1024x768-76,
+            1152x864-70, 1280x1024-61, 1024x768-85, 1280x1024-70,
+            1152x864-84, 1280x1024-76, 1280x1024-85
+ 
+
+Known Issues
+============
+
+The XFree86 FBDev server has been reported not to work, since tgafb doesn't do
+mmap(). Running the standard XF86_TGA server from XFree86 3.3.x works fine for
+me, however this server does not do acceleration, which make certain operations
+quite slow. Support for acceleration is being progressively integrated in
+XFree86 4.x.
+
+When running tgafb in resolutions higher than 640x480, on switching VCs from
+tgafb to XF86_TGA 3.3.x, the entire screen is not re-drawn and must be manually
+refreshed. This is an X server problem, not a tgafb problem, and is fixed in
+XFree86 4.0.
+
+Enjoy!
