The HP Pavilion tx25135cl is a 12.1″ laptop tablet. It comes with an AMD Turion X2 RM-70 processor clocked at 2.0Ghz per core. Along with an ATi Radeon 3200 HD, this makes it a part of the AMD Puma platform. It has 3GB of RAM, a 250GB hard drive, and is usually pre-installed with Windows Vista Home Premium.
All installation work was done on the Ubuntu alternative installer.
Things that need fixing:
Installation:
You will need to pass nolapic and acpi=off as kernel options, both for installation and normal boot. Not doing this results in a thermal warning (and subsequently a forced shutdown). Specifying other combinations is prone to causing a kernel panic (and subsequently a hard system lockup as a result).
Ethernet:
Realtek Ethernet is severely broken with the RTL8111/816B that gets loaded as stock.
A bug report for this is here: https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/141343
The fastest way to fix this is to use Jameson William’s fixup. You will want to load the file there onto a USB stick. From a fresh Hardy install (alternative installer), the patch program was not installed, so you may need to grab a deb as well.
Grab the fixup here (read the instructions for it and install): http://www.jamesonwilliams.com/hardy-r8168.html
If you end up needing the patch utility, you can find it here: http://us.archive.ubuntu.com/ubuntu/pool/main/p/patch/
Select the appropriate architecture, download it onto your USB stick, and as root on the affected computer, issue a `dpkg -i patch_[version here]_[architecture here].deb` to install it.
Wireless:
Broadcom BCM4328 a/b/g/n
This Broadcom chipset is VERY nice, it does 802.11 a/b/g/n. However it doesn’t get recognized as stock, and thus it falls over on itself:

This did not work for me on the cl, even though others with similar configurations had working wireless configurations. This may change in the future.
At this point, I decided to return the laptop due to time constraints (I was not able to get to work on the video or tablet features). Hopefully this post helps somebody out.
It needs more code
