I'm still not having much luck getting a Megahertz XJ10BT card to work
in an older 486 laptop with even the 2001/03/24 sources.

However with an older CC10BT card *and* an XJ10BT card both installed
the second card probes properly and actually works:

note the above is a lie -- the card is actually an older Megahertz model

[[ Note that I've edited out many instances of "APM get event: unknown
error code (0x530b)", and as well suspends don't work (the machine drops
down and springs right back to life even with cron, syslogd, etc. all
killed off) and stand-by mode hangs the system -- i.e. there's something
not quite right about APM support on this machine too, and APM_NO_V12
doesn't help (though it improves the meaningfulness of "apm -v"
output).... ]]

Note also that detatching just sm1 does nothing (no "detached" event is
reported).

However detatching sm2 first works:

| sm2 detached
| sm1 detached

but re-installing just the X-Jack card desn't work (note the "unknown
chip id, etc.):

| pcmcia0: CIS version PCMCIA 2.0 or 2.1
| pcmcia0: CIS info: Megahertz, CC10BT/2, PCMCIA 10BASE-T/2 ETHERNET ADAPTER, 00008616C6E4

| sm1 at pcmcia0 function 0 port 0x400-0x40f: Megahertz X-JACK Ethernet
| sm1: unknown chip id 15, revision 15, buffer size: 0
| sm1: MAC address 00:00:86:16:c6:e4, default media UTP
| sm1 detached

If the interface is configured with an address then all that happens is
a "sm1 device timeout" message is printed when transmit interrupts are
not received by the kernel (though packets are transmitted, at least the
initial ARP who-has requests are seen on the wire).

Re-inserting first the old CC10BT card and then the XJ10BT X-Jack card
makes it work again:

| pcmcia0: CIS version PCMCIA 2.0 or 2.1
| pcmcia0: CIS info: Megahertz, CC10BT/2, PCMCIA 10BASE-T/2 ETHERNET ADAPTER, 0000860595E2

IIRC the same sequencing works for the CC10BT, but I don't have the
coax dongle handy to test again just at this moment....
