More info plus a possible patch.
/sys/devices/platform/orion-ehci.0/modalias exists which contains
the string platform:orion-ehci
And:
$ modprobe --show-depends platform:orion-ehci
insmod /lib/modules/2.6.26-1-orion5x/kernel/drivers/usb/core/usbcore.ko
insmod /lib/modules/2.6.26-1-orion5x/kernel/drivers/usb/host/ehci-hcd.ko
So maybe all we have to do is take all modalias files into account.
This patch does this:

With this patch, there are two differences in the initramfs:
1) the correct module (ehci_hcd) is included.
and
2) conf/modules contains some more stuff:

I'm not sure if it's a problem that these modules are followed by so
much garbarge. But the initramfs boots.
The new log from the modalias parsing (with all the non-modalias stuff
removed):

Anyway, the new initramfs with this patch works for me. But I've no
idea if the modalias parsing has any side effects.
