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!

+Kernel driver i2c-via
+Supported adapters:
+ * VIA Technologies, InC. VT82C586B
+ Datasheet: Publicly available at the VIA website
+Author: Kyösti Mälkki <kmalkki@cc.hut.fi>
+i2c-via is an i2c bus driver for motherboards with VIA chipset.
+The following VIA pci chipsets are supported:
+ - MVP3, VP3, VP2/97, VPX/97
+ - others with South bridge VT82C586B
+Your lspci listing must show this :
+ Bridge: VIA Technologies, Inc. VT82C586B ACPI (rev 10)
+ Problems?
+ Q: You have VT82C586B on the motherboard, but not in the listing.
+ A: Go to your BIOS setup, section PCI devices or similar.
+ Turn USB support on, and try again.
+ Q: No error messages, but still i2c doesn't seem to work.
+ A: This can happen. This driver uses the pins VIA recommends in their
+ datasheets, but there are several ways the motherboard manufacturer
+ can actually wire the lines.
