The problem seems not to be in tulip driver, but in apm or power management.
I see, with some debugging added by me :
[ 488.585707] eth0: Digital DS21142/43 Tulip rev 17 at Port 0xec00, 00:00:f8:02:cf:08, IRQ 11.
[ 508.888374] eth0: 21143 10baseT link beat good.
[ 530.754453] apm: BIOS version 1.1 Flags 0x03 (Driver version 1.16ac)
[ 530.754723] apm: entry f690:7ca cseg16 f690 dseg 40 cseg len ffff, dseg len ffff
[ 531.016684] apm: Connection version 1.1
[ 531.018853] apm: AC on line, battery status unknown, battery life unknown
[ 531.028277] apm: battery flag 0x80, battery life unknown
[ 864.060751] apm: received system standby notify
[ 864.063111] check_events : calling standby()
[ 1141.088550] apm: received system standby resume notify
[ 1141.090195] check_events : calling dpm_resume_end(PMSG_RESUME)
[ 1141.096173] tulip_resume
I do not see there a call to tulip_suspend after the call to standby(),
but I think there should be one.
