It is a known limitation of some HP BIOSes... they have an extremely
severe bug which sometimes bites.  The workaround you mention (using
localboot 0x80 or chain.c32 hd0) is pretty much the only option.

I and Michael Brown were in touch with HP about this and the bug has
been root-caused; unfortunately it is utterly infeasible to work around
this particular breakage.
