SiS IDE Controller 5513 [sis5513] patch, try 1

Supported (tested) kernels:
2.6.12-1.1381_FC3

Problem:
On original Fedora kernel there is no support to DMA on the SiS IDE controller model 5513.
Go figure why on the file [sis5513] there is no string to address DMA setup to the "SiS5513" chipset, maybe sooner support and no rework after that.

Approach:
Modify the module source to recognise the controller hardware.

Remarks:
RPM kernel spec file part will be covered on the kernel specific part.

1. Get and install the kernel source that applies :

2. Patch to the file [sis5513.c]:
