4 sharp rom kernels to choose from

The clock speed is also remembered between suspend/resume cycles (although not reboots) when changed directly (as ced demonstrated) or by using the clock change app.

I might see about removing the pre-emptive patch as it doesn\'t give a significant speed boost (it\'s turning off the PXA250 bug workaround that doubles the speed) and it seems to cause more trouble than its worth. I think I\'ve found a problem with the patch and the VNC server. I\'ll also reduce the number of kernel binaries to just one if I get time to do this.

Any progress on this?  This sounds like a good compromise between performance enhancement and compatibility problems/other unintended consequences.

BTW, in the \"is this a sick joke?\" dept., my SL-5600 with PXA 255 processor arrived with a kernel that I assume has the PXA250 cache workaround, since it benchmarks at about 160 VAX MIPS with dhry21.

And now with special kernel...VAX MIPS 271!
