Fedora Core 6 on a Compaq Presario V6000

• Fedora Core 6 installed fine without any kernel parameters. The only things that didn't work right out of the box were the widescreen resolution (1280x800) and the WiFi adapter.
• WiFi. You can get source drivers from Intel but I had a version mismatch with other modules. So the easy way was to upgrade the kernel to 2.6.19-1.2911.6.5.fc6, then install the following RPMs from atrpms : ieee80211; ipw3945; ipw3945-ucode and ipw3945d. Add a modprobe script that starts the daemon (/sbin/ipw3945d), then /sbin/ifup eth1 and everything should work.
• Widescreen. X.org detects the chipset correctly and loads the i810 driver. But apparently the BIOS of the video card doesn't report the 1280x800 mode, so even though X.org detects the mode and adds a modeline, and I also added a modeline manually, I kept getting Not using mode "1280x800" (no mode of this name). To work around this, there's a tool called 915resolution which patches the mode table in the BIOS (or something like that). Call this tool somewhere in your init scripts (I put it in /etc/rc.d/rc.local) and add the 1280x800 video mode (915resolution 0x38 1280 800 24). After this X.org should recognize the mode without any problem.
