I don't follow 2.5 dev (yet). I merely follow Andre's work on 2.4 and
code a new chipset capabilities detection code in order to support newer
Is the v0.13 driver driver already forward ported to 2.5 by somebody ?
If there's a need (some 2.5 developpers needing a more uptodate driver
and uncomfortable with forward porting IDE chipset drivers), I'll do it...

Unless the SiS620 is not compatable with the 630 IDE support spec or
affected by some bugs I corrected for PIO mode timings (unlikely as they
were unnoticed for a quiet long time) since sis5513.c v0.11 this should
not be an IDE chipset problem.

Hum, 486 SiS chipsets might bring pain to me also...
I've received several bugreports for old SiS IDE chipset (ie pre ATA66)
that I couldn't solve without disabling the SiS driver or passing
"ide=nodma". I've triple-checked the specs and couldn't see the problem.
