You need to get a recent benh kernel and enable the APM emulation
feature. The X server uses /dev/apm_bios (IIRC) to keep aware of the
power state, and to stop using the graphics acceleration engine and such
when a suspennd occurs. I'm running Linux on a 366 MHz FireWire iBook,
so I can tell you that it can be made to work.

Use a recent benh kernel, and enable support for I2C, the I2C /proc
interface, and the KeyWest I2C driver. That will allow the PowerMac
dmasound driver to control volume and enable power-management mode on
the DACA chip (which the round iBooks use).
