* Olicom 22.8k and 33.6k modems need to activate the right
* CFE. The odd formula below replicates the sequence of cfes
* that have multiple resources:
* 9, 11, 13, 15, 0 + 9
* 25, 27, 29, 31, 16 + 9
* 41, 43, 45, 47, 32 + 9
* 57, 59, 61, 63 48 + 9
* (entries 8, 24, 40 and 56 are single resoruce cfes)
* Fortunately the code that enables and disables the multiple
* fuctions of the card won't mess with the lower bit for cards
* that aren't stanards conforming MFC cards (which these olicom
* cards aren't).
*
* Note: These cards still don't get interrupts for reasons
* unknown, even when the right cfe is selected. There's likely
* something in the CCR that needs to be manually tweaked, but
* the COR bits seem to all be used. Bit 0 and 3 are always set
* and the other bits select the config to use. Maybe one of those
* two bits needs to be cleared, or there's something else in the
* CCR that needs tweaking. The pattern of resources suggests
* bit 0 turns on the ethernet, however...
