Subject: [PATCH 2.6.18_rc4 1/1] via82cxxx: Add support for 8237A ISA bridge

Hello,

Some mainboards (e.g. Asrock 775Dual-VSTA) come with a
PCI_DEVICE_ID_VIA_82C586_1 IDE controller together with a VIA VT8237A
southbridge.

While the corresponding PCI ID is already present in pci_ids.h, the via82cxxx
driver doesn't know about it yet and disables DMA.

Signed-off-by: Alexander Hans <alex@...ns.de>
