Hello,

I have some odd boot messages (new since switching from kernel 2.2 to 2.4) for the HP Netserver LD Pro (Pentium Pro 200MHz). I'd like to know if there is a hardware or configuration problem, or whether it's "just normal" (the "reserved twice").

It's "just normal". The MP-table parsing code reserves space for the MP table and then parses the table. But the table also reserves its own space.
