27 | * SiS southbridge has a LM78-like chip integrated on the same IC. |
28 | * This driver is a customized copy of lm78.c | |

31 | * Version PCI ID PCI Revision | |
32 | * 1 1039/0008 AF or less | |
33 | * 2 1039/0008 B0 or greater | |
34 | * | |
35 | * Note: these chips contain a 0008 device which is incompatible with the | |
36 | * 5595. We recognize these by the presence of the listed | |
37 | * "blacklist" PCI ID and refuse to load. | |
