Here is a patch to add limited acpi support to the epia board. This is purely for testing purposes. I can't guarantee it will work, however on my 500Mhz Epia board it seems to be ok. There are changes to the mainboard Config/Options.lb so you will need to rebuild the target, before compiling.
This patch allows Linux to poweroff the mainboard correctly. A shutdown -r also works, however, it should be noted that this will not be the same a a physical reset as I don't think the chipset supports it, at least I can't find any references to a reset register.
There are some differences from my original BIOS. It reports only 2 CPU throttling states, however mine reports 16 as I believe this is correct. I have not been able to test this. Not even sure how to go about it.
Hopefully the ACPI supports S1 and S4 states (not tested) however as there are currently no ACPI wakeup devices, if you suspend the board it probably won't wakeup. My main aim was to get power down working. I may have a go at including some wakeup functionality when I get time and get my head around the ACPI spec a little better.
best of luck Ben

This works great here. The system power button doesn't shut the system down though (holding it cuts power of course)
A shutdown -r also works, however, it should be noted that this will not be the same a a physical reset as I don't think the chipset supports it, at least I can't find any references to a reset register.
There are some differences from my original BIOS. It reports only 2 CPU throttling states, however mine reports 16 as I believe this is correct. I have not been able to test this. Not even sure how to go about it.
Mine also reports 16 throttling states, and setting them works fine (echo # > /proc/acpi/processor/CPU0/throttling, where # is the desired throttling state). I compared speeds using the distributed.net client benchmark, and speed matched what was expected for each throttling state.

good to hear it works ok on your board. I am not to sure how to do the power button, but will have a look. Also need to enable wakeup events, or at least put some commented code in there so people can enable/disable the ones they want.
Thanks also for the pci dump. The differences between the original bios and LB appear to be mostly the same on your board also. At least the registers I think may be causing the problem. I'll try setting them on my board and see if it helps with the hangs, not that they happen very frequently at the moment.
