Here is the roundup for Fedora 12, RedHat's latest release.
PASS - Asus system board with AMD-64 X2, upgrade from F11.
FAIL - Acer Aspire One AO751h netbook, no video driver for poulsbo chipset yet.
FAIL - Acer Aspire 5517-5136 laptop, went into endless reboots .. so I used Ubuntu 9.10 ... the wireless (Broadcom STA drivers) gave me a bit of a head scratching, but, the solution was easily found on the web. Dual boot with Win7.
