indeed <sigh> i have had CPU scaling working with CPUFreq on my dell
D600 (Dell is rapidly becoming the Ikea of computer vendors :) but the
same problems with ACPI sleep. (S1 works, S3 doesn't, although S5 does)

when ACPI does work then when bus modules are loading i get a lot of: 

dsobject-0189: *** Warning: Buffer created with zero length in AML

this is using the ACPI4Linux patches against 2.4.20 and  2.4.21-rc1

ACPI didn't load at all in 2.4.21-rc1-ac2 though (i don't have the exact
message to hand, but something about signatures being incorrect maybe) 

i have settled on a reasonable compromise of using swsusp with ACPI on
2.4.20 (using a patch from http://alor.antifork.org/acpi-swsusp/) which
is acceptable and works (i think you need at least S5 to work for swsusp
to turn the machine off)  

/proc/acpi/processor/CPU0/performance reports the requisite number of P
states but the associated CPU speed for all of them is 0Mhz 

also weirdly i can change the P state from P0 but only to P5 or P6 and
then i can't change it back again (although this doesn't seem to have a
great deal of effect) 

throttling  changing works (i.e. the T state changes) but i'm not
entirely convinced it is actually doing anything.
