For the record: Compaq Presario 700EA notebook. Red Hat 7.2, kernel.org
2.4.18 fully ACPI and ac97_codec patched, gcc 3.0.4, pppd 2.4.1-3. I
normally use kppp out of gnome, but wvdial and the manual stuff all work
too. I tell the modem to connect with 115200 but connect speed is 57600.


I don't know what the ppp_async module is. I don't use it ...

Yes, it works for me. But I didn't update to the June 25th driver, since
it's not applicable to my hardware. I used the *tar.gz package.

Presumably you have a reason to want to use the 2.4.19 kernel, I could
think of a couple offhand. However, I shy away from prerelease kernels -
and at the last count there were no ACPI patches for it, which my Compaq
