i am not familiar with the PXA255,
but i believe that ur network driver (for CS8900) should implement
IOCTL calls
(such as IOCTL_POWER_CAPABILITIES, IOCTL_POWER_SET,.. etc)
 and power management functions such as powerUp() and powerDown() so
it know what to do when the system is suspending /resuimg.
for suspending, i think u need to place the ethernet chip in some low
power mode.
upon resuming, i think u need to re-initialize the chip and certain
registers and rebind to NDIS, etc.....

is ur system locking up after resume or just the ethernet stops
working?

i am new to wince/device drivers (8 months so far) so Guru's might have
better answer for u
hope that helps
