Yes, I did, and it has since been documented in the PCMCIA HOWTO, section 2.3, subsection "Card readers for desktop systems":
For Chase CardPORT and Altec ISA card readers using the Cirrus PD6722 ISA-to-PCMCIA bridge, the i82365 driver should be loaded with a ``has_ring=0'' parameter to prevent irq 15 conflicts.
I had been trying the option "has_ring=1", which I didn't know was the default.
