It seems that my message hasn't yet shown up on lkml, so I suppose to have 
some mail problem :(

To see if this helps, I've removed attachments, replacing it with urls.

I've collected more data; Here you can find .config for all three cases:

2.6.18-mm3 (working) http://members.ferrara.linux.it/cova/config-2.6.18-mm3
2.6.19-rc5 (working) http://members.ferrara.linux.it/cova/config-2.6.19-rc5
2.6.19-rc5-mm1 (not working) 
http://members.ferrara.linux.it/cova/config-2.6.19-rc5-mm1

and dmesg for 2.6.18-mm3 and 2.6.19-rc5. I've seen that I've saved the dmesg 
with nvidia driver inserted; I can't, right now, recreate the files without 
nvidia driver loaded, but as the issue happens before the driver is loaded 
maybe the information can be useful anyway. I'll made a non tainted dmesg as 
soon as possible, if needed.

http://members.ferrara.linux.it/cova/dmesg-2.6.18-mm3
http://members.ferrara.linux.it/cova/dmesg-2.6.19-rc5

I'm trying to get the dmesg for 2.6.19-rc-mm1 (the non-working one), but I've 
to find a serial cable :)

Anyway, I've seen this message on dmesg, that seems interesting (copied by 
hand, please forgive any mistake):

PCI: Unable to reserve I/O region #1:8@1f0 for device 0000:00:1f.2
ata_piix: probe of 0000:00:1f.2 failed with error -16

Of course, lspci for that device gives:

00:1f.2 IDE interface: Intel Corporation 82801EB (ICH5) SATA Controller (rev 
02) (prog-if 8a [Master SecP PriP])
        Subsystem: ABIT Computer Corp. Unknown device 1014
        Flags: bus master, 66MHz, medium devsel, latency 0, IRQ 17
