 Hmm, erratum #2 is about status output pins.  I suppose you mean erratum
#5.  But then it applies to V3.0, too.

 Then the bit is r/w, so how about toggling it instead of panicking? 
With an informational message like:

printk(KERN_ERR "Firmware bug: 32-byte I-cache line size unsupported for
the R4000...\n");
printk(KERN_ERR "... fixing up to 16-byte size.\n");

Of course that probably requires a temporary cache inhibition and

 Would you care to code that or should I look into it?
