I have all the grief on a Sempron/ATI  system

model name      : Mobile AMD Sempron(tm) Processor 3600+

If I specify nolapic,noapic or acpi=noirq on kernel boot, the machine  
goes  in  to VERY slow motion  (5 minutes to boot!)   the noapictimer 
option was the magic keyword in my case and I am going to dig in to the 
code to see what things this setting fudges with :-)
