Hm, maybe that's not the best word? (my English is clearly lacking 
sometimes). What I meant is that this is a pointer to the RSDP. I've 
probably used "hint" here because in FreeBSD the position of the RSDP is 
passed from the loader to the kernel as "hint.acpi.0.rsdp". Let me know if 
you would like me to rephrase this.

Roger.
