MWNZ, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc4

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  [VIA EPIA M910] SATA drive reduced to UDMA/33

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I have an EPIA M910 (VX900 chipset) board with the latest BIOS (BIOS
  1.01 2012/02/17 I2100101.zip). I have a Seagate SATA ST32000542AS
  drive installed and a SATA PIONEER BDR-207D Blu-Ray burner installed
  for backups. I have no IDE devices (the IDE slots on the mobo are
  empty). In the latest BIOS, the options to select SATA or IDE modes
  have been removed. When booting into Linux, these are clearly set by
  the BIOS to IDE mode and this cannot be changed. The kernel driver
  also unfortunately identifies the fictitious IDE cables as 40-wire,
  which reduces the speed from UDMA/133 to UDMA/33. This  seriously
  negatively impacts on the usability of this machine. A selection of
  the relevant portion of the dmesg output is appended to illustrate the
  problem. It looks like this might be an issue in the pata_via driver.
  The fictitious IDE "cable" should rather be detected as 80-wire to
  enable the UDMA/133 mode. Ideally, it would be useful to be able to
  select SATA mode through a kernel option and not have to rely on that
  option being set in the BIOS, but I am unsure of whether that would be
  possible. I have confirmed this issue with Ubuntu 12.10 as well.
