Now... I have a Sony Vaio FX-103 with the RICOH RL5C476 not the 75. The laptop has 192 MB of RAM (not the standard 64) and a 10gb harddisk. Mandrake 8.1 with a 2.4.16 kernel with a USB PCI IRQ Routing patch to make USB work (yes I am waiting heavily for the ACPI stuff!).
Anyhow, no matter what I do (including your patch modified to work on the different controller) I cannot get two cards to work inside this laptop.
Have you tried Ingo's IRQ rate limiter? Perhaps someone forgets to send an EOI to the hardware, and then everything locks up due to a level triggered interrupt that remains active forever.
