[PATCH] VIA VT8235 PCI quirk Like many other southbridges from different manufacturers, VIA VT8235 chip has two non-standard BARs for power management and SMBus registers (see the datasheet at http://www.via.com.tw). This new quirk routine fixes boot problem with 2.6.13-rc2/rc6 kernels on Targa Visionary 811 Athlon64 laptop, as reported by Mikael Pettersson <[EMAIL PROTECTED]>.
