That solved the warning.

The current pnp boot messages:

PnP: PNP BIOS installation structure at 0xc00f7470
PnP: PNP BIOS version 1.0, entry at f0000:a905, dseg at 400
PnP: 15 devices detected total
PNPBIOS: request ports [PNP0c01]:
PNPBIOS: request ports [PNP0c02]: 0x4d0-0x4d2 0x1000-0x1040
0x1040-0x1050
PNPBIOS: request ports [PNP0c02]:
PNPBIOS: request ports [PNP0c02]:

What is strange is that PNPBIOS reports 15 devices detected, and lspnp
detects 18 (00 - 17):

[root@LNX /root]# lspnp
00 PNP0c02 system peripheral: other
01 PNP0c01 memory controller: RAM
02 PNP0200 system peripheral: DMA controller
03 PNP0000 system peripheral: programmable interrupt controller
04 PNP0100 system peripheral: system timer
05 PNP0b00 system peripheral: real time clock
06 PNP0303 input device: keyboard
07 PNP0c04 reserved: other
08 PNP0800 multimedia controller: audio
09 PNP0a03 bridge controller: PCI
0a PNP0c02 bridge controller: ISA
0b PNP0c02 memory controller: RAM
0c PNP0c02 memory controller: RAM
11 PNP0f13 input device: mouse
15 PNP0700 mass storage device: floppy
17 PNP0400 communications device: AT parallel port
