So, back from rebooting...
Intrepid live CD with "acpi=off" --> network OK Intrepid live CD without "acpi=off" (but with "noapic nolapic", otherwise it hangs) --> no network
So: probably a problem with ACPI. The card seems to have a sleep mode, see the Realtek page:
"Features [...] * Supports power down/link down power saving"
