I suspect the power management (ACPI) to be the cause. The driver 
itself didn't change much between 2.4 and 2.6.

... and also does not complain about reading the EEPROM. Not being 
able to read data from the card is a typical symptom of power related 
problems.

Try booting with acpi=off.
Try updating BIOS and/or modify power related options in BIOS.
