+AltiVec Kernel Support
+CONFIG_ALTIVEC
+  This option enables kernel support for the Altivec extensions to the
+  PowerPC processor. The kernel currently supports saving and restoring
+  altivec registers, and turning on the 'altivec enable' bit so user
+  processes can execute altivec instructions.
+
+  This option is only usefully if you have a processor that supports 
+  altivec (G4, otherwise known as 74xx series), but does not have
+  any affect on a non-altivec cpu (it does, however add code to the
+  kernel).
+
+  If in doubt, say Y here.
+
+Thermal Management Support
+CONFIG_TAU
+  G3 and G4 processors have an on-chip temperature sensor called the
+  'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
+  temperature within 2-4 degrees celcius. This option shows the current
+  on-die temperature in /proc/cpuinfo if the cpu supports it.
+
+  Unfortunately, on some chip revisions, this sensor is very inaccurate
+  and in some cases, does not work at all, so don't assume the cpu
+  temp is actually what /proc/cpuinfo says it is.
+
+Interrupt driven TAU driver
+CONFIG_TAU_INT
+  The TAU supports an interrupt driven mode which causes an interrupt
+  whenever the temperature goes out of range. This is the fastest way
+  to get notified the temp has exceeded a range. With this option off,
+  a timer is used to re-check the temperature periodically.
+
+  However, on some cpus it appears that the TAU interrupt hardware
+  is buggy and can cause a situation which would lead unexplained hard
+  lockups.
+
+  Unless you are extending the TAU driver, or enjoy kernel/hardware
+  debugging, leave this option off.
+
+Average high and low temp
+CONFIG_TAU_AVERAGE
+  The TAU hardware can compare the temperature to an upper and lower bound.
+  The default behavior is to show both the upper and lower bound in 
+  /proc/cpuinfo. If the range is large, the temperature is either changing
+  a lot, or the TAU hardware is broken (likely on some G4's). If the range
+  is small (around 4 degrees), the temperature is relatively stable.
+
+Support for CUDA based PowerMacs
+CONFIG_ADB_CUDA
+  This provides support for CUDA based Power Macintosh systems.  This
+  includes most OldWorld PowerMacs, the first generation iMacs, the
+  Blue&White G3 and the Yikes G4 (PCI Graphics).  All later models
+  should use CONFIG_ADB_PMU instead.
