Last changes for 2.0.2

* Fixed FORCE_PIIX4_ENABLE bus (misspelled function call)
* Added Kyösti's mail about the VIA chipset to the doc directory, as
  temporary placeholder

 Many, many things. Most notably:
 
+* At least the bit-lp and bit-velle modules do no detection on loading;
+  ask Simon whether this is possible to add.
 * Check whether the FAN count divisors in the lm78 module are correct
   (probably not!); correct gl518sm changed-fan_div_but_did_not_update_fans
 * Wouldn't it be better to display all natural voltages for the LM78 chip,

+Read i2c/README.bitmb.
+Your /proc/pci or lspci must show VT82C586B (note the last B)
+to make it work. This is an upgraded version of VT82C586/A with USB and
+ACPI support. The i2c-lines are accessed through the ACPI part.
+
+This is my PCI bus data:
+
+00:07.3 Bridge: VIA Technologies, Inc. VT82C586B ACPI (rev 10)
+        Flags: medium devsel
+
+South bridge VT82C586B is in these chipsets: MVP3, VP3, VP2/97, VPX/97
+
+I don't see the last two PCI devices if USB is not enabled in BIOS setup.
+BTW, my motherboard is FIC VA-503+.
+
+Hope this helps for now, I will write better documentation some day.

 (i2c) bit-mb: algo-bit i2c-core

 (i2c) bit-lp: algo-bit i2c-core
   I2C bus through the parallel port, Philips interface
+  Do not insert this module unless you are sure you have this interface;
