Not exactly. The driver uses the PCI Vendor ID/Device ID Configuration
registers to identify the chipset. lspci used the same information to
identify a "Realtek... RTL-8110SC/8169SC...". It is a known device.
The driver does not care about the Subsystem ID ("10ec" above) so there
is nothing to worry about here.

Have your tried 2.6.23-git-latest or at least a post 2.6.23-rc1 kernel ?
