You will need the ipw2200 kernel module and firmware to use your wireless card. Mandriva should have an RPM for both, if they are not installed automatically.
The X server should use the i810 driver for the video card. You can also enable DRI for hardware acceleration. This should be done automatically by the installer.
According to this link (http://www.phoronix.com/lch/?k=entry...t=HP%20dv1000)
, everything should "just work" except for the media card reader (but keep in mind that was using Ubuntu 6.06). However, if the card reader is anything like my dv5000t's card reader, the latest 2.6.19 series kernel should provide an experimental driver for it. Even if something doesn't work out of the box, the fact that Ubuntu could run it indicates that it is still possible.
