Think it'll be fine. Just wanted to add two things.
If it doesn't appear in Network Neighbourhood, (even under Entire Network etc), try opening explorer and actually type \\laptop_name.
As a last resort, share a folder on your Windows 98 machine, rather than the other way around. I know my Windows 7 machine has no problems at all dropping files on Windows 98, but it can take ages for it to appear in the list, so I manually type it's name.
I don't have NetBEUI though, just TCP/IP with 'Allow NetBIOS over TCP/IP' checked.
