Time has passed without further mention of this problem. Today I took some time to discover exactly where the boot process was hanging. I found the place.
In drivers/usb/host/pci-quirks.c, in function quirk_usb_disable_ehci (should start around line 211) there is a stanza that reads:
/* always say Linux will own the hardware * by setting EHCI_USBLEGSUP_OS. */
pci_write_config_byte(pdev, offset + 3, 1);
On my sapphire athlon64 motherboard (see the thread for more details), this call never returns (without generating any output). I commented it out, and now the EHCI subsystem works OK (currently running 2.6.16rc2).
I do not know what the right patch should be.
