2.6.11:
BIOS-provided physical RAM map:
ACPI: IRQ0 used by override.
ACPI: IRQ2 used by override.
ACPI: IRQ9 used by override.
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
ide0: BM-DMA at 0xfc00-0xfc07, BIOS settings: hda:DMA, hdb:DMA
ide1: BM-DMA at 0xfc08-0xfc0f, BIOS settings: hdc:DMA, hdd:DMA

2.6.12:

ACPI: IRQ2 used by override.
ACPI: IRQ9 used by override.
Boot video device is 0000:01:00.0

VP_IDE: port 0x01f0 already claimed by ide0
VP_IDE: port 0x0170 already claimed by ide1
and dmesg | grep VP_IDE gives:
2.6.11:
VP_IDE: IDE controller at PCI slot 0000:00:0f.1
VP_IDE: chipset revision 6
VP_IDE: not 100% native mode: will probe irqs later
VP_IDE: VIA vt8237 (rev 00) IDE UDMA133 controller on pci0000:00:0f.1
2.6.12:
VP_IDE: IDE controller at PCI slot 0000:00:0f.1
VP_IDE: chipset revision 6
VP_IDE: not 100% native mode: will probe irqs later
VP_IDE: VIA vt8237 (rev 00) IDE UDMA133 controller on pci0000:00:0f.1
VP_IDE: port 0x01f0 already claimed by ide0
VP_IDE: port 0x0170 already claimed by ide1
VP_IDE: neither IDE port enabled (BIOS)
And when doing lsmod, 2.6.11 has via82cxxx immediately after ide-core and way
before ide-generic, while 2.6.12 has ide-generic followed by via82cxxx.
Using /etc/modules doesn't work, since discover and company already have done
the damage.
