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.
