Re: via 6420 pata/sata controller

I downloaded new kernel 2.6.11, applied your's via82cxxx.c patch and 
compiled it (.config was derived "make oldconfig" from 2.6.8 kernel from 
Debian Sarge 3.1).

I created initrd.img with this settings:
/etc/mkinitrd/mkinitrd.conf
--- cut here ---
MODULES=dep
--- cut here ---

/etc/mkinitrd/modules
###
jbd
ext3
ide-core
via82cxxx

I boot PC with this settings:
/etc/modules
###
ide-cd
via82cxxx

Results:
Everything is the same, dmesg, lspci, lspci -n, cat /proc/ioports, lsmod 
as the last email.

Controller still don't working :'(.

PS: I don't add anything into pci_ids.h, I only applied your's 
via82cxxx.c patch:
#define PCI_DEVICE_ID_VIA_6420 0x4149

Your's Sincerely
