One more idea to check is if the irq of the IDE device is mapped at the 
same IRQ line and described correctly in the open firmware device tree. 
You may need info from a real machine for that, I've tried to search for 
it but could not find any device tree dumps or info on how irqs are mapped 
in the real hardware. Since Linux can find it it's probably OK but maybe 
Solaris expects the irq to be mapped somewhere else or gets the info on 
this from some other place than Linux and that could have a bug? Not sure 
if this helps but I have no better idea.
