XO-4 camera not working in Linux

XO-4 camera works under OpenFirmware but not in Linux.
The issue is that no image data is captured. No interrupts arrive.
Mitch's debugging suggestions:
I would use cforth or sdkit to inspect the CCIC IRQ mask and status registers - 20a02c io@ . and 20a030 io@ . then I would look at the interrupt routing for irq42 - 2820a8 io@ . - should have the 0x20 bit set then at the int42 status register - 2821cc io@ . and the int42 mask register - 2821b4 and the irq1 status register - 28213c - should have the 0x400 bit set (bit 10, 42 - 32 = 10)
