SiS5513 & 2.4.22-1.2115.nptl

[Daniel]

Hi Mark,

try passing to the kernel  during boot

ide=nodma

(may be ide1=nodma or ide2=nodma see if this is valid)

These are paramters  to the installation program  (that doesn't  work  
during installation)  but they may function to the kernel (who knows? 
this may be your luck day. Okay, this is just a try, forget abou it if 
it doesn't work)
