Hi,

i have tried with your updated version:

$ cat /proc/cpuinfo
processor       : 0
cpu             : PPC970, altivec supported
clock           : 1800.000000MHz
revision        : 2.2

processor       : 1
cpu             : PPC970, altivec supported
clock           : 1800.000000MHz
revision        : 2.2

timebase        : 33333333
machine         : PowerMac7,2
motherboard     : PowerMac7,2 MacRISC4 Power Macintosh
detected as     : 336 (PowerMac G5)
pmac flags      : 00000000
pmac-generation : NewWorld

just wondering, is the timebase suppose to look like this? and where are
the bogomips gone?

$ cat /proc/version
Linux version 2.6.11-pseries (sven@pegasos2) (gcc version 3.4.4 (Debian 3.4.4-0ubuntu3)) #1 SMP Fri Jun 3 17:32:34 UTC 2005

$ grep PM72 /boot/config-2.6.11-p*
/boot/config-2.6.11-power4-smp:CONFIG_THERM_PM72=y
/boot/config-2.6.11-pseries:# CONFIG_THERM_PM72 is not set

it is still as noisy as in an aircraft here :)

$ grep ALTIVEC /boot/config-2.6.11-p*
/boot/config-2.6.11-power4-smp:# CONFIG_ALTIVEC is not set
/boot/config-2.6.11-pseries:CONFIG_ALTIVEC=y

nice, thanks
