sata_sis on 2.4.27 vs 2.6.8

[Facundo Ariel Perez <facundo.ariel.perez@gmail.com>]

I'm running a debian sarge on PIV / asus motherboard / using the  181
chipset for my serial ata 80 gb drive.
It installs and runs ok using kernel 2.4.27 - but when I upgrade to
kernel 2.6.8 the systems crash on while booting just after showing the
disk's detailed information.
I've tryed both a pre-compiled kernel and a self-made kernel from
sources ... In both cases, the result is the same.
Apparently, the problem is related with the module sata_sis ( I've tried
it as a module and compiled into kernel ).
Ideas ?
Thanks in advance.
Regards.
