attached you can find a patch that should fix i2c-sis630 driver for
2.6.0-X kernel. With i2c-sis630 from stock 2.6.0-X we have oops and
driver was not correct registered against i2c-core.

Changes:
	1) fixed a oops while modprobing
	2) added check for buffer overflow for i2c block data read transaction
	3) added 'force' modprobe parameter. It's allow more easily
	   testing for not yet supported SiS chips.
