OK, I'll give you PCMCIA wireless cards.  I've lost more hours of sleep
to those than any other piece of hardware.  Fortunately, they are
getting hard to find.  I've got a couple of questionable capability if
you want them.  Strange about the printer. The LJ1100 comes in with a
"perfect" at linux-printing.org:

There seems to be a hardware issue with that device though.

You certainly have more data points than I for dealing with legacy
hardware and Linux, but I think that since the turn to USB peripherals
support has gotten much better in Open Source.  On my laptop (Dell
Vostro 1500 fully functional with Hardy), USB devices almost always just
work. In the cases of a TV stick and a WWAN stick, I needed a driver
update but these work out of the box with ubuntu 9.04.

ATI:  Open source driver xf86-video-ati (http://www.x.org/wiki/radeon)

  * R100/R200 (Radeon 7000 – Radeon 9250) and R300/R400/R500 (Radeon
9500 – Radeon X1950) class chips:
          o 2D: accelerated (EXA), stable
          o XVideo: accelerated and tear free, stable
          o 3D: accelerated, stable
    * R600/R700 class chips (Radeon HD 2300 – Radeon HD 4890):
          o 2D: accelerated (EXA), a new feature (see
radeon:r6xx_r7xx_branch)
          o XVideo: accelerated and tear free, a new feature (see
radeon:r6xx_r7xx_branch)
          o 3D: experimental, development in two places simultaneously;
mesa r6xx-r7xx-support, r6xx-rewrite, both need drm r6xx-r7xx-3d |
instructions for usage at radeonhd:experimental_3D

Review of xf86-video-ati in ubuntu 9.04:

Bottom line: Almost as good as the proprietary driver.

Nvidia: Open source driver nouveau (http://nouveau.freedesktop.org/wiki/)
2D acceleration. No 3D.

Review of nouveau in ubuntu 9.04:
http://www.phoronix.com/scan.php?page=article&item=ubuntu_904_nouveau&num=1

Bottom line: Stick with the proprietary driver.
