pppd (initially) fails to negotiate PPPoE connection

I'm trying to connect to an ADSL modem under SuSE 9.0 (rp-pppoe-3.5,
smpppd-1.06, ppp-2.4.1). When I use the original SuSE kernel 2.4.21,
everything works fine:

pppd[8098]: Plugin pppoe.so loaded.
pppd[8098]: PPPoE Plugin Initialized
pppd[8098]: Plugin passwordfd.so loaded.
pppd[8098]: pppd 2.4.1 started by root, uid 0
pppd[8098]: Sending PADI
pppd[8098]: HOST_UNIQ successful match
pppd[8098]: HOST_UNIQ successful match
pppd[8098]: Got connection: b6e
pppd[8098]: Connecting PPPoE socket: 00:90:1a:40:df:1a 6e0b eth0 0x8089
pppd[8098]: Using interface ppp0
pppd[8098]: Connect: ppp0 <--> eth0
pppd[8098]: Setting MTU to 1492.
pppd[8098]: Couldn't increase MRU to 1500
pppd[8098]: Setting MTU to 1492.
...
pppd[8098]: Script /etc/ppp/ip-up finished (pid 8131), status = 0x0

But when I start my self-compiled 2.6.9, pppd fails:

pppd[1951]: PPPoE Plugin Initialized
pppd[1951]: Plugin passwordfd.so loaded.
pppd[1951]: pppd 2.4.1 started by root, uid 0
pppd[1951]: Sending PADI
pppd[1951]: HOST_UNIQ successful match
pppd[1951]: Failed to negotiate PPPoE connection: 25 Inappropriate ioctl for device
pppd[1951]: Exit.

However, if I simply wait until booting is finished, and restart the
network service later, pppd suddenly succeeds again. What might cause
this? Does the newer kernel export some functionality into a module
that I do not load soon enough, or does it try to do one thing after
another faster then the old one?

Probably timing. Some program is not up during the boot sequence when you
start pppd that pppd needs. Eg networking.
